Kosei's seafood ceviche (27,000 won), built on autumn produce, and the monkfish liver flounder sushi, 6 pieces (21,000 won), went down well with draft beer, and the fig-and-seafood pairing plus the rich monkfish liver over flounder stood out. With bar seats for solo drinkers and a calm room for anniversaries or small groups, Kosei is one of the quieter bars in this part of Seoul. ## Good to know - **Address**: 14 Eungam-ro 21ga-gil, 1F Unit 101, Eunpyeong-gu, Seoul - **Hours**: Mon–Sat 17:00–01:00 the next day (last order 23:50) - **Closed**: Every Sunday - **Ordering policy**: One alcoholic drink or one beverage required per person - **Good to know**: Reservations accepted, groups welcome, no-kids zone - **Parking**: No private lot; Eungam 3-dong public parking lot is a 3–4 minute walk - **Seafood ceviche**: 27,000 won - **Monkfish liver flounder sushi**: 6 pieces, 21,000 won *as written by the visitor on Sep 22, 2026* ![Main image of Kosei, an izakaya near Eunam Station](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-01-1kt4h-966.webp) ![Table spread of Japanese dishes at Kosei](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-02-u3hdn-1200.webp) ![Exterior of Kosei izakaya in an Eunam-dong alley](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-03-kgmqc-m-966.webp) ## What kind of place is Kosei? I heard there was an izakaya with great atmosphere in Eunam-dong, so I went to check out Kosei. Yay!!! It's a spot where you can taste Japanese dishes made with fresh, seasonal ingredients — an izakaya near Eunam Station that offers something a bit different from the usual bar food. ### Kosei hours, address and ordering rules - Address: 14 Eungam-ro 21ga-gil, 1F 101, Eunpyeong-gu, Seoul, South Korea - Hours: Monday–Saturday 17:00–01:00 the next day - Last order: 23:50 - Closed: every Sunday - Ordering policy: one drink or beverage order required per person - Other: reservations available, group-friendly, no kids allowed ### Parking at Kosei and how to get there There's no dedicated parking lot for the restaurant. If you're driving, search for 'Eungam 3-dong public parking lot' — it's about a 3–4 minute walk from there to Kosei. From Eunam Station, take Exit 4, walk along Bulgwang Stream, and cross the first bridge. Head into the alley by the GS25 convenience store, and you'll spot Kosei diagonally to the right of the Chamdarae Park intersection. From Saejeol Station, it's about 587m from Exit 1 — a nice stroll along Bulgwang Stream. I actually walked from home. The weather's been so good lately! ## A Japanese izakaya tucked in an Eungam-dong alley ![Wood-finished exterior of Kosei](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-04-ydfi8-966.webp) This Eunam Station bar had a calm, atmospheric feel right from its wood-finished exterior. ![Interior of Kosei with wood-toned tables and red walls](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-05-ubro8-966.webp) Inside, wood-toned tables mix with red walls for a warm, cozy vibe. There's also bar seating facing the kitchen, which looked great for a quiet solo drink and meal. It really did feel comfortable for solo drinking, and it also seemed like a good spot for a date night or a small gathering. While I was eating, an elderly couple sat across from each other, enjoying food and drinks together affectionately — it looked so lovely and full of atmosphere. It made me want to still be out enjoying good food together like that when I'm older. This is an Eunpyeong-gu bar that suits days when you'd rather have a calm conversation over a meal than sit in a loud, rowdy bar. ## Kosei's table setting and menu lineup Once seated, plates and utensils were neatly arranged on a wooden tray. ![Plates and utensils neatly arranged on a wooden tray](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-06-czfxy-966.webp) ![Table setting at Kosei](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-07-uqut5-966.webp) ![Page of the Kosei menu](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-08-67vmc-966.webp) ![Menu page listing sashimi dishes](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-09-3zomr-966.webp) ![Menu page listing sushi dishes](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-10-bz5c3-966.webp) ![Menu page listing grilled dishes](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-11-r8dr3-966.webp) ![Menu page listing tempura dishes](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-12-bhwrz-966.webp) ![Menu page listing noodle dishes](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-13-gtwzk-966.webp) ![Menu page listing hot pot dishes](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-14-1yrie-966.webp) ![Sake menu page](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-15-1sexa-966.webp) ![Soju and beer menu page](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-16-fixo5-966.webp) ![Wine menu page](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-17-3mpva-966.webp) ![Last page of Kosei's drink menu](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-18-15pr3-966.webp) Looking at the menu, there was a wide range from sashimi to sushi, grilled dishes, tempura, noodles, and hot pot. The drink lineup was also varied, with sake, soju, beer, and wine, so it was easy to pick something to match the food. We ordered the seafood ceviche and the monkfish liver flounder sushi, paired with a cold draft beer. ## Seafood ceviche, 27,000 won The seafood ceviche is a Japanese-style ceviche made with autumn seafood, vegetables, and fruit. ![A plate of Kosei's seafood ceviche](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-19-1h0vl-966.webp) Generously cut, fresh seafood came piled high with figs, crisp vegetables, and pear. Topped with a clear, jelly-like garnish and sauce, it looked as vibrant as it tasted. ![Close-up of seafood ceviche topped with figs and pear](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-20-cf552-966.webp) Each bite delivered the clean flavor of the seafood, the subtle sweetness of the fruit, and the crisp texture of the vegetables all at once. It was my first time having ceviche with figs, and surprisingly, they went really well with the seafood. ![Seafood ceviche with generously sized ingredients](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-21-1bzx3-966.webp) The ingredients were cut big and served generously, so it was fun to eat spoonful by spoonful. It's a refreshing, appetite-opening dish — a great choice for the first order of the night. ## Monkfish liver flounder sushi, 6 pieces, 21,000 won This dish tops flounder sushi with sweetly braised monkfish liver. ![A plate of monkfish liver flounder sushi, 6 pieces](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-22-15odp-966.webp) Glossy flounder was generously topped with monkfish liver, finished with a touch of wasabi. The chewy, clean flavor of the flounder paired with the rich, savory taste of the monkfish liver made for a really special combination. The wasabi cut through the richness of the liver cleanly, so it never felt heavy — I kept reaching for more. ![Flounder sushi topped with monkfish liver and wasabi](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-23-visi7-966.webp) It's not the kind of sushi you'd normally come across, and it felt like a real showcase of Kosei's distinctive style. ![Monkfish liver flounder sushi served with draft beer](https://img.superchart.com/images/kosei-izakaya-eungam-seafood-ceviche/kosei-izakaya-eungam-seafood-ceviche-24-n31wy-m-966.webp) It paired well with the draft beer too — really enjoyed it. ## Is Kosei worth it? Final thoughts on this Eungam Station bar Kosei is a place where you can enjoy distinctive Japanese dishes made with fresh seafood and seasonal ingredients. The seafood ceviche had a refreshing combination of fruit and seafood, and the monkfish liver flounder sushi stood out for the harmony between the clean flounder and the rich liver. With bar seating for solo drinkers and a calm mood between tables, it also suits a date night or a small gathering. If you want to try something other than the usual bar snacks in Eunam-dong, give Kosei a visit. It's a quiet izakaya near Eunam Station, perfect for conversation over a drink. ## Where it is - Kosei (코세이) - 14 Eungam-ro 21ga-gil, 1F 101, Eunpyeong-gu, Seoul, South Korea - 서울특별시 은평구 응암로21가길 14 1층 101호 - 37.5949065, 126.9174657 - Google Maps: https://www.google.com/maps/search/%EC%BD%94%EC%84%B8%EC%9D%B4/@37.5949065,126.9174657,17z --- Superchart · https://superchart.com/en/@coffee-at-leisure/kosei-izakaya-eungam-seafood-ceviche/ · https://superchart.com/llms.txt
