Picture this: it’s a 35°C July afternoon in Seoul, the humidity is pushing “unbearable,” and outside a restaurant, a long queue of people is patiently waiting — to sit down and eat piping-hot chicken soup, sweat dripping down their faces. If you see this, chances are it’s Boknal. Of all the days on the Korean calendar, these are the three hottest — and Koreans mark them by eating the hottest food they can find. To the uninitiated traveler, it looks like madness. To Koreans, it’s a 2,000-year-old summer ritual that still runs the country. This guide covers what Boknal actually is, why samgyetang owns the day, the eight best places to eat it in Seoul, and every other boyangsik Koreans reach for when summer hits.
The Short Answer
- 2026 Boknal dates = Chobok July 15 · Jungbok July 25 · Malbok August 14. It's a wolbok year (20 days between Jungbok and Malbok), so expect the heat to overstay its welcome.
- Bok (伏) doesn't mean luck — it means to lie prostrate. As in, autumn's cool energy surrenders to summer's heat. Three times.
- Eating the hottest food on the hottest day is called yiyeolchiyeol. The poster child is, unequivocally, samgyetang.
- Seoul's big three: Tosokchon (Seochon/Gyeongbokgung) · Goryeo Samgyetang (City Hall, Michelin-listed) · Baekje Samgyetang (Myeongdong). Expect ₩18,000–26,000 per person.
- On Boknal itself, count on an hour's wait at lunch. Samgyetang is a year-round food — come a day later and the line disappears.
What Exactly Is Boknal? — Sambok and the 2026 Dates
Boknal refers to the three hottest days on the Korean lunisolar calendar. Chobok (初伏), Jungbok (中伏), and Malbok (末伏) are collectively called Sambok (三伏), and the brutal heat that defines this stretch is known as sambok-deowi. They aren’t public holidays, but what you eat on these days is such a shared national ritual that it makes the evening news.
📅 2026 Boknal Dates
| Name | 2026 Date | Day | How It’s Determined |
|---|---|---|---|
| Chobok | July 15 | Wednesday | 3rd gyeong-il (庚日) after the summer solstice |
| Jungbok | July 25 | Saturday | 4th gyeong-il after the summer solstice |
| Malbok | August 14 | Friday | 1st gyeong-il after ipchu (start of autumn) |
The dates shift every year because Sambok is anchored to the 10 Heavenly Stems (cheongan) — specifically, days containing gyeong (庚). Chobok and Jungbok follow the summer solstice in 10-day increments, but Malbok uses ipchu as its reference, which means the gap between Jungbok and Malbok can be 10 days or 20. 2026 is a wolbok (越伏) year, with a full 20 days between Jungbok (July 25) and Malbok (August 14). Korean folk wisdom says wolbok years bring a longer, more stubborn tail of late-summer heat.
The Character Behind 'Bok (伏)'
Boknal's bok is not the bok (福) that means luck or fortune. It's bok (伏) — to lie prostrate, to surrender, to crouch down. One interpretation: it's so hot that humans, like dogs, should lie flat on the ground. The more poetic reading: autumn's cool energy confronts summer's scorching energy and is forced to its knees — three times. Either way, the message is the same: summer is still winning. Real autumn only begins once Sambok has passed.
Why Eat the Hottest Food on the Hottest Day? — Yiyeolchiyeol
If you had to sum up Korean summer food culture in one word, it’d be yiyeolchiyeol (以熱治熱) — fight heat with heat.
Here’s the logic. Traditional Korean medicine sees summer as a season when the body’s heat rushes to the surface, leaving the internal organs and gut surprisingly cold. Throw icy drinks and chilled food at an already-cold core, and your digestive strength and energy (gi) plummet. So you warm your insides with hot broth to bring things back into balance. Layer on top of that the idea of boyangsik (補養食) — restorative foods that replenish the protein and stamina you’ve been sweating out all summer — and you have a complete philosophy.
And honestly? There’s a physiological thread here that isn’t folk nonsense. Eat something hot, you sweat. Sweat evaporates, your body temperature drops. Same reason Indians reach for curry in 40°C heat and Mexicans sip steaming caldo when the humidity peaks.
Field Notes for Travelers
Walk through any office district at lunchtime on Boknal — Gwanghwamun, City Hall, Yeouido, Gangnam. You'll see entire teams streaming into samgyetang restaurants together. Treating your team to samgyetang on Boknal is a long-standing Korean workplace tradition. Some companies, like Samsung Electronics, serve tens of thousands of bowls in their in-house cafeterias on these days.
The Origins of Sambok — From 7th-Century BCE China to Samgyetang
The earliest written record of Sambok dates to 676 BCE, the second year of Duke De of Qin in ancient China. Sima Qian’s Records of the Grand Historian (史記) notes that the first Sambok rites were held that year, with sacrificial meat distributed among the people. The custom crossed into the Korean peninsula and became fully entrenched during the Joseon dynasty.
But here’s the part most people miss: the food eaten on Boknal hasn’t always been samgyetang. Through the late Joseon period, the Boknal dish of choice was gaejangguk — dog meat soup. 19th-century texts record the practice of slaughtering dogs during Sambok. Then, in the mid-20th century, two things happened: Korea’s poultry industry scaled up massively, and ginseng became affordable for ordinary households. Samgyetang quietly and completely took over. Today, Boknal = samgyetang is essentially official, and with the 2024 law banning dog meat consumption, gaejangguk is fading into history.
What Is Samgyetang? — And How to Eat It Right
Samgyetang (蔘鷄湯) is a 30-to-50-day-old young chicken, its cavity stuffed with glutinous rice, ginseng, jujubes, garlic, and chestnuts, then simmered whole in a stone pot until the meat pulls away from the bone. It’s a one-person dish. The name says exactly what it is: ginseng (蔘) + chicken (鷄) + soup (湯).
The crucial detail most first-timers miss: the broth is deliberately, almost shockingly, under-seasoned. A lot of foreign visitors take one spoonful and think, “This is bland.” That’s not a mistake — it’s the design. You”re meant to mix the salt and pepper served on the side into a little dipping pile, then dip each piece of chicken as you go. You can also add pinches of salt directly to the broth, bit by bit, until it hits your personal sweet spot.
How to Eat Samgyetang — The Local Way
- Mix salt and pepper on your side plate to make a dipping seasoning.
- Use your chopsticks and spoon to pull the chicken apart and pick the meat off the bone. Using your hands is totally fine (they''ll give you a bowl for the bones).
- Dig out the glutinous rice stuffing from inside the chicken and stir it into the broth — this is the real highlight.
- The ginseng root? You can eat it. It's earthy and slightly bitter. If it's too tough to chew, leaving it is perfectly acceptable.
- Many places serve a complimentary shot of ginseng liquor (insamju). Knocking it back in one go is the custom.
- Kkakdugi (radish kimchi) and cabbage kimchi are unlimited refills. They cut through the richness perfectly.

1. Tosokchon Samgyetang — The ‘National Samgyetang’ in a Seochon Hanok
Just steps from Gyeongbokgung Station in Seochon’s Chebu-dong, this is a sprawling complex of interconnected hanok with over 40 years of doing one thing only: samgyetang. It’s designated a Traditional Local Food Restaurant by the Seoul Metropolitan Government, and on Chobok every year, it’s the first place TV news cameras show up. The broth here isn’t just milky — it has a faint gray-green tint, because they grind black sesame (heugimja) and nuts into the stock. The result is deeper, nuttier, and noticeably thicker than anywhere else. It became known as the “Presidential Samgyetang” after the late President Roh Moo-hyun was spotted as a regular, and the nickname stuck. Location-wise, this is the single most practical choice for travelers — it’s perfectly placed before or after a morning at Gyeongbokgung. On Boknal and weekend lunchtimes, the queue is no joke: aim for 10 AM, right after opening.
5 Jahamun-ro 5-gil, Jongno-gu · 5 min walk from Gyeongbokgung Station Exit 2 · roughly 10:00–21:00 · Samgyetang from ₩20,000
2. Goryeo Samgyetang — Michelin-Listed Samgyetang Behind City Hall
Tucked into the alleyways of the Seosomun office district near City Hall Station, this is one of the very few samgyetang specialists to be listed in the Michelin Guide Seoul year after year. The broth is clean, clear, and orthodox — the polar opposite of Tosokchon’s nutty richness. The signature move is the wild cultivated ginseng samgyetang (sansam samgyetang), which adds a layer of cultivated wild ginseng root on top of the standard bird. A lot of regulars pay the extra few thousand won to upgrade. It’s a short walk from Deoksugung Palace, City Hall, and Jeongdong — easy to slot into a sightseeing loop. On weekdays at lunch, expect the place to be packed with office workers. The upside: turnover is fast, so even if there’s a line, it moves.
1 Seosomun-ro 11-gil, Jung-gu · 5 min walk from City Hall Station · Weekdays 10:30–21:00 / Weekends 10:30–20:30 · Samgyetang ₩20,000 / Sansam Samgyetang ₩26,000
3. Baekje Samgyetang — The Most Foreigner-Friendly Spot in Myeongdong
Right in the thick of Myeongdong’s shopping maze, this place has done nothing but samgyetang for over 40 years. A huge chunk of the clientele is Japanese, Chinese, and Taiwanese travelers, which means foreign-language menus and service are the most polished of any spot on this list. The hours are traveler-friendly too — open 9 AM to 10 PM. The ginseng samgyetang is the go-to, and the ginseng fragrance here hits more assertively than at most other places. If you’re weaving samgyetang into a Myeongdong shopping-and-snacking afternoon, this is your easiest, most comfortable entry point. First-timer? Start here.
8-10 Myeongdong 8-gil, Jung-gu · 5 min walk from Myeongdong Station / Euljiro 1-ga Station · roughly 09:00–22:00 (L.O. 21:00) · Ginseng Samgyetang ₩24,000
4. Samdae Samgye Jangin — A Seocho Institution Since 1973
In Banpo, Seocho-gu, this is a third-generation samgyetang house that opened its doors in 1973. It’s been designated a Seoul Heritage Business (Baengnyeon-gage) and has appeared in the Michelin Guide. What sets it apart — and you’ll notice this the moment the pot lands — is the broth’s texture and color: they blend mugwort, pine nuts, and mung beans into a paste that turns the soup thick, green-tinged, and deeply earthy. If standard samgyetang feels too delicate for you, or you’re after something that tastes more unapologetically like herbal medicine, this is your spot. Good access from the Express Bus Terminal and Seorae Village.
56-3 Banpo-daero 28-gil, Seocho-gu · near Express Bus Terminal Station · ₩20,000s
5. Wonjo Hosu Samgyetang — Yeongdeungpo’s Local Legend with Perilla Seed Broth
Tucked away on Dorim-ro in Yeongdeungpo, this place has sat at or near the top of Dining Code’s Seoul samgyetang rankings for years. It’s a neighborhood institution that locals flock to while tourists rarely venture out this far — which is exactly why you should go. The signature is the deulkkae samgyetang: a generous amount of ground perilla seeds stirred into the broth, making it nutty, creamy, and impossibly rich. Basic samgyetang starts around ₩18,000 — noticeably gentler on the wallet than the tourist-circuit heavyweights. If you want “the samgyetang spot Seoulites actually swear by,” this is number one.
274-1 Dorim-ro, Yeongdeungpo-gu · near Singil Station / Yeongdeungpo Market Station · Samgyetang from ₩18,000 · Deulkkae samgyetang priced separately
6. Gobong Samgyetang Myeongdong — Premium Brew with Phellinus Mushroom
Alongside Baekje, this is Myeongdong’s other traveler-heavy samgyetang destination. The differentiator is the sanghwang-beoseot (Phellinus linteus) samgyetang — brewed with a medicinal mushroom that gives the broth a darker color and an earthy, almost smoky depth you won’t find anywhere else. The dining room is larger than most and the turnover is brisk, so if you’re in Myeongdong and baulk at the Baekje queue, this is a solid plan B. Group travelers are accommodated with zero fuss.
Myeongdong area, Jung-gu · walking distance from Myeongdong Station · ₩20,000s
7. Jangsu Hanbang Samgyetang — Gwanghwamun Office Workers’ Lunchtime Mecca
With locations in the basements of Gwanghwamun, Yeouido, and Gongdeok office buildings, this is a medicinal-herb samgyetang specialist that runs on the lunch-hour rhythms of Korea’s white-collar workforce. The broth is steeped with a blend of traditional medicinal herbs, and the menu includes a bangyetang (half-chicken) option — a lifesaver if a whole bird feels like too much. Particularly good for solo female travelers or families with kids. On weekdays, avoid the 12:00–1:00 PM crush; the surrounding office towers empty into this place.
B1, 13 Seodaemun-ro 5-gil, Jongno-gu (Gwanghwamun branch) · near Gwanghwamun Station Exit 8 · Weekdays roughly 11:00–21:30 · ₩20,000s
8. Yongsan Samgyetang — A Samgakji Classic Near Yongridan-gil
A long-standing neighborhood spot near Samgakji Station and the Yongridan-gil strip, this place has drawn its share of celebrities and TV personalities over the years. Alongside the medicinal-herb samgyetang, they also do an excellent dak-bokkeum-tang (spicy braised chicken) — if you’re with a group, ordering one samgyetang and one dak-bokkeum-tang to share is a pro move. Yongridan-gil’s cafes and bars are the hot thing right now, so this works beautifully as a fortifying base layer before an evening of exploring the neighborhood.

Beyond Samgyetang — Korea's Other Summer Boyangsik
Samgyetang may be the undisputed heavyweight champion, but Boknal food culture has never been a one-dish show. Joseon-era records mention yukgaejang, jeonbokjuk (abalone porridge), chueotang, grilled eel, and minyeotang (croaker soup) as summer staples. Koreans group all of these under the umbrella term boyangsik (補養食) — literally, “foods that replenish and restore the body.”
Yukgaejang — The Fiery Soup Born from Gaejangguk’s Transformation
Beef brisket, hand-shredded along the grain, simmered with scallions, taro stems, and bracken in a broth stained deep red with gochugaru. The name gives away its origin story: gaejang in yukgaejang comes from gaejangguk — the original dog meat soup that this beef version was created to replace. It’s a classic yiyeolchiyeol dish: spicy enough to make you sweat, hot enough to cool you down. Today, it’s also the soup Koreans most associate with funeral halls, which tells you something about its status as a deeply familiar comfort food. In Seoul, old-school hanok restaurants inside the old city walls serve excellent versions without much fuss.
Grilled Eel (Jangeo-gui) — Korea’s King of Stamina Food
Freshwater eel (pungcheon-jangeo), grilled over charcoal and finished with either salt or a sweet-soy glaze. The proper way to eat it: wrapped in a perilla leaf with a tangle of fresh ginger. Summer is peak eel season, and with its dense payload of protein and unsaturated fatty acids, eel is synonymous with restoring spent energy in the Korean imagination. One caveat: it’s not cheap. Expect to pay around ₩40,000 per serving, which puts it in “treat yourself” territory. In Seoul, eel restaurants cluster around Togjeong-ro in Mapo, Chungmuro, and the back alleys behind Seoul Station.
Chueotang (Seoul-Style ‘Chutang’) — Yonggeumok in Mugyo-dong, Since 1932
Loach — the humble freshwater fish — simmered and then ground whole, bones and all, into a thick, calcium-rich soup. Here’s what makes this dish fascinating: it’s a completely different food depending on where you are in Korea. The Namwon style (Jeolla-do) uses a doenjang base and comes out mild, thick, and earthy. Seoul-style chutang, by contrast, builds its broth from beef bones, brisket, and tripe — it comes out red and fiery, closer to yukgaejang than anything else. The definitive Seoul chutang is Yonggeumok in Mugyo-dong, which opened in 1932 and has been at it for over 90 years. Whole loach in the bowl is standard; you can ask for it ground if you prefer.
Mugyo-dong, Jung-gu · walking distance from City Hall Station / Euljiro 1-ga Station · founded 1932
Kongguksu — The Only Cold Boyangsik, and Jinju Hoegwan Near City Hall
If the thought of hot soup on a hot day makes you wilt, kongguksu is your answer. Soybeans are soaked, boiled, and ground into a creamy, nutty broth, then poured over thin wheat noodles with a handful of ice cubes. It arrives unseasoned — you add salt (or sugar) at the table, and Koreans are fiercely divided into salt and sugar camps depending on which region they’re from. The definitive Seoul spot is Jinju Hoegwan near City Hall, open since 1962 and now run by the third generation. In summer, they essentially operate as a single-menu kongguksu restaurant. A crucial heads-up: kongguksu is generally a March-through-November seasonal dish. If you’re visiting in winter, call ahead.
26 Sejong-daero 11-gil, Jung-gu · 3 min walk from City Hall Station · roughly 11:00–21:00 (break 14:00–15:00) · closed Sundays · Kongguksu from ₩16,000
Jeonbokjuk · Minyeotang — Recovery Porridge and the Aristocrat’s Fish
Jeonbokjuk is abalone — including the green-tinged innards — slow-cooked into a creamy porridge. It’s gentle enough to serve as hospital recovery food, but satisfying enough that you’ll crave it on any heat-drained afternoon when the idea of chewing feels like effort. Abalone porridge is easy to find at juk (porridge) chains across Seoul. Minyeotang, on the other hand, is a rarer beast — a croaker soup that Joseon-era royalty and aristocrats considered “the finest fish of summer.” July and August are peak season, and it remains a special-occasion dish rather than an everyday meal, priced accordingly.
Finish with Patbingsu
You’ve sweat through a bowl of yiyeolchiyeol. Now, the closer: patbingsu. Finely shaved ice (or snowflake milk ice, these days) piled with sweet red beans, chewy injeolmi rice cake, and a drizzle of condensed milk. Korean-style bingsu is the undisputed king of summer desserts, and the classic Boknal playbook goes: samgyetang → walk it off → find a cafe → order bingsu. It’s not optional; it’s the full ritual.
Boknal Survival Tips for Travelers
Headed Out for Boknal Samgyetang? Here's What to Know
- Dodge peak hour. 11:30 AM–1:00 PM on Boknal is the worst. Aim for 10–11 AM or 2–4 PM and you'll walk right in.
- Skip the day entirely. Samgyetang isn't a seasonal special — it's on the menu 365 days a year. Come the day after Boknal and the queue is half as long.
- You don't need cash. Most well-known samgyetang spots take cards and mobile payments, though old-school neighborhood joints are worth confirming.
- Watch the ginseng liquor. That complimentary shot of insamju can clock in above 30% ABV. It hits harder than it tastes.
- Vegetarian / halal travelers. Samgyetang is chicken-broth-based and there's no real workaround. Kongguksu or patbingsu are your most realistic alternatives.
- Don't count on strong AC. Old hanok-style restaurants with floor seating can have weak air conditioning. Bring a handkerchief. You'll sweat — lean into it.
