Walk about five minutes from Exit 5 of Hoehyeon Station toward Namdaemun Market, and the first thing you notice is a small shop with a line that starts in the morning. Hotteok usually means a sweet pancake oozing honey and sugar, but the star here is yachae hotteok, a savory version filled with glass noodles and vegetables. Several hotteok fry at once on an oiled iron griddle, while one person pulls the dough, another flips and another presses each one flat, all moving in quick rhythm. The dough is made every morning from 6 a.m., and the shop closes once it sells out. Dip a hotteok, crisp outside and chewy inside, lightly in soy sauce and take a bite, and the early-morning line suddenly makes sense. Years have passed, yet the line in front of this shop is as long as ever. Honey (seed) hotteok and red bean hotteok are also on offer, so try a sweet one and a savory one side by side.

If you are spending the day around Myeongdong and Namdaemun, it makes a good stop on a morning walk; next comes bindaetteok at a market more than 100 years old in Jongno. Walk about three minutes from Exit 7 of Jongno 5(o)-ga Station, and the nutty smell of frying oil greets you before you even reach the alley. Gwangjang Market (광장시장) is introduced as Korea's first permanent market, more than 100 years old, with around 5,000 shops, and it was selected as one of the "Korea Tourism 100" spots. If you had to pick one signature food here, it would be bindaetteok. On busy days the line in front of a shop stretches close to 50 m. At Sunhee-ne Bindaetteok (순희네빈대떡), finely ground mung bean batter is fried thick on the griddle. Try the mung bean bindaetteok, crisp at the edges and fluffy in the middle, with a meatball pancake (gogi wanja) on the side. Sit on a narrow stool by the griddle and tear off piece after piece, and you realize you have stepped right into a Korean lunch hour in the middle of the market. The shop is closed on Tuesdays, so be sure to check before you plan your day.

It makes a good lunch on a day around Jongno and Dongdaemun; next, head to a tteokbokki shop in a Myeongdong alley. Tteokbokki ranked ninth when Gallup Korea asked Koreans about their favorite Korean dishes in 2024, making it the best-loved street food on the list. The easiest place to try it on your trip is Myeongdong. Walk about five minutes from Exit 5 of Euljiro 1(il)-ga Station into the alley toward Myeongdong Cathedral, and a small snack shop with a red sign, Shinsegae Tteokbokki (신세계떡볶이), comes into view. Just a few steps from the crowded main street, it keeps the feel of a neighborhood snack shop that has stood in Myeongdong for a long time. Featured on the TV show Saenghwal-ui Dalin (생활의 달인), the shop's secret is garlic. A thick special sauce loaded with garlic soaks deep into plump, chewy rice cakes. It looks fiery red but is milder than you expect, and a sweet-and-savory depth comes through first. Besides tteokbokki, the shop also sells sundae, odeng, fried snacks and pan-fried dumplings. You can watch the tteokbokki being made right at the front, and while there are a few seats inside, most customers stand and finish a plate quickly. Like true street food, drop by between shopping stops and eat it standing up.

If tteokbokki is a year-round favorite, some snacks come back to the streets only in winter. When the cold wind starts to blow, the first thing Koreans think of is bungeoppang, a fish-shaped pastry. In a 2017 survey that asked 2,400 people in their 20s to 50s what food comes to mind when they hear "winter," bungeoppang ranked first with 25.0%, and 65.1% of the winter snack shops residents registered on Daangn Market's (당근마켓) "Winter Snack Map" were bungeoppang shops (winter 2022–2023). The stalls are no longer on every corner as they once were, so Koreans call neighborhoods with plenty of them "bung-sekwon" and share stall locations, opening status and prices on map apps. Near Namyeong Station, the stop right after Seoul Station, one shop starts baking at 7 a.m. Namyeong Station Chapssal Ingeoppang (남영역찹쌀잉어빵) bakes ingeoppang, a close cousin of bungeoppang, with glutinous rice batter. Take a paper bag of them fresh from the mold, and the warmth in your palms alone makes winter feel welcome. If you want to find bungeoppang near your hotel, open a map app and follow the reviews locals leave.

If you need a hearty dinner rather than a snack, the sundae alley of Sillim-dong in southern Seoul is the answer. Three minutes from Exit 4 of Sillim Station, you reach a building packed with sundae restaurants. In the 1970s, a few shops stir-frying sundae at a market in Sillim-dong grew into today's Sundae Town. When Seoul National University moved to the neighborhood in 1975, students living on their own and people studying for state exams poured in, and cheap, filling stir-fried sundae became their go-to meal. After Line 2's Sillim Station opened in 1984, people came from all over Seoul for it, and the alley grew even busier. The dish to try here is baek-sundae, stir-fried white without red seasoning. Dip sundae stir-fried on an iron plate with perilla leaves and vegetables into the dipping sauce, and nuttiness comes first, followed by a spicy kick. Ordering it alongside yangnyeom sundae bokkeum, stir-fried in gochujang sauce, makes for a fun comparison. The restaurant stays open until 2 a.m., so it works for a late dinner too.

Last comes a skewer you don't need to seek out, because you'll find it almost anywhere you ride the subway. Ride the subway in Seoul and you often come across small snack stands selling tteokbokki, fish cakes and gimbap inside stations and underground passages. They aren't destinations in themselves, but for Koreans they are the most familiar street food for a quick bite between transfers. You could say the market stall's fish cake skewer has moved into the subway station. Among them, Marizzang (마리짱) is a snack brand that has grown mainly in subway stations, known for bite-size mini gimbap and tteokbokki. At Marizzang Jamsil (마리짱 잠실점) in the underground passage of Jamsil Station, you can try fish cake coated in a spicy seasoning, one skewer at a time. Fill a paper cup with broth and sip it standing, and the warmth quickly reaches your cold fingertips. Open from 6:30 a.m. to 11 p.m., it's an easy stop on your way to Lotte World or back to your hotel late at night. Menus and hours differ by store, so at other stations, step into any snack stand that catches your eye and start with a fish cake skewer.

Yachae hotteok at Namdaemun Market, bindaetteok at Gwangjang Market, garlicky tteokbokki in a Myeongdong alley, ingeoppang near Namyeong Station, sundae in Sillim-dong and spicy fish cake in the subway. They are all flavors you crave more as the weather turns cold. None of them is expensive, yet every plate holds the days of people who have lived in those alleys for a long time. Is there a better way to taste Korea up close? On this trip, instead of a restaurant reservation, try standing at the end of a locals' line. Prices may change, so please check the latest information for each shop before you visit.
