# Sunday night chicken nanban at a Sinnonhyeon izakaya: Izakaya Goko - By Taeho Wi (https://superchart.com/en/@eulji-neon-glass/) - Written Sep 19, 2026 - Local places › Bars › Gangnam, Seoul - Sponsored: This post was written as a sponsored store visit. - English edition: https://superchart.com/en/@eulji-neon-glass/sinnonhyeon-izakaya-goko-chicken-nanban-highball/ - Also in: [한국어](https://superchart.com/ko/@eulji-neon-glass/sinnonhyeon-izakaya-goko-chicken-nanban-highball/index.md) ## In short Izakaya Goko Gangnam Sinnonhyeon Branch is an izakaya on the 2nd floor of Bansuk Building on Bongeunsa-ro 2-gil, between Gangnam Station and Sinnonhyeon Station in Seoul. On a Sunday visit after 9pm, the order was flounder sio sanhap (flounder sashimi with salt gimbap), chicken nanban, a Goko highball and a Suntory highball, and the signature Goko highball tasted better than the Suntory because the whiskey aroma was not overpowering. For a Gangnam Station bar where sashimi and fried dishes share one table, Izakaya Goko is a solid pick. ## Good to know - **Address**: 2nd floor, Bansuk Building, 21 Bongeunsa-ro 2-gil, Gangnam-gu, Seoul - **Hours**: Daily 4:30 PM – 2:00 AM - **Last order**: 12:00 AM - **Ordered**: Flounder sio sanhap, chicken nanban, Goko highball, Suntory highball - **Seating**: Open window seats, counter (dachi) tables, private space - **Complimentary snack**: Popcorn *as written by the visitor on Sep 19, 2026* The address is 21 Bongeunsa-ro 2-gil, Gangnam-gu, Seoul, on the 2nd floor of Bansuk Building.

Between Gangnam Station and Sinnonhyeon Station Izakaya Goko sits right between Gangnam Station and Sinnonhyeon Station! A lot of people looking for a Gangnam Station bar also check out Sinnonhyeon, and this area has such a great mix of restaurants and bars that it works well as a dinner meetup spot too haha ![Sign directing to the 2nd floor of Bansuk Building for Izakaya Goko](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-03-1o7s3-900.webp) ![Wood-tone interior of Izakaya Goko](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-04-69ua6-900.webp) ## Izakaya Goko was full even at 9pm on a Sunday Walking up to the 2nd floor and into the store, the wood-tone interior and soft lighting blended together nicely! I visited past 9pm on a Sunday, and figured it'd be quiet since it was getting late and the next day was Monday, but there were so many customers..👍🏻 I snapped the interior photos in a hurry right before leaving haha ![Softly lit dining hall at Izakaya Goko](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-05-12jyx-900.webp) ![Open window seating at Izakaya Goko](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-06-1424e-900.webp) The window seats had the windows open, which gave a nice open feel. Not stuffy at all, great for a refreshing drink haha There's also a standing counter table and a private space, so it's good for a cozy drink too 🫶🏻 ![Menu board at Izakaya Goko](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-07-gcomg-900.webp) ## What we ordered at Izakaya Goko From the Izakaya Goko menu we ordered flounder sio sanhap, chicken nanban, a Goko highball, and a Suntory highball! The menu lineup was so varied it seemed like a great place to do a full first-round-to-second-round night in one spot lol - Flounder sio sanhap - Chicken nanban - Goko highball - Suntory highball It was great being able to enjoy sashimi and fried food together 💟 Sashimi plus fried snacks made a great pairing, and with the highball on top, the drinks just kept going down smoothly! ![Goko highball with complimentary popcorn](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-08-1ww8k-900.webp) ### Goko highball vs Suntory highball: which one wins? The highballs we ordered came out first, along with complimentary popcorn 🍿 It was salty-sweet and easy to snack on. The Goko highball is the signature drink named after the shop, so I was curious and ordered it — and it was actually tastier than the Suntory! The whiskey scent wasn't too strong, so I'd recommend it to lightweights too 👍🏻 ![Table set with flounder sio sanhap and chicken nanban](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-09-1wq68-1200.webp) Soon after, the flounder sio sanhap and chicken nanban arrived! They looked delicious from the start, and with sashimi and fried food both generously laid out, the table felt completely full 💛 ![A plate of flounder sio sanhap at Izakaya Goko](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-10-1vvvg-900.webp) ![Sio sanhap plate with flounder sashimi and gimbap together](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-11-pago3-900.webp) ### What does flounder sio sanhap (flounder sashimi with salt gimbap) taste like? I'd wanted to try flounder salt gimbap ever since seeing it on Kang Min-kyung's YouTube channel, and it turned out to have a totally different charm from regular sashimi ✨ I was curious what the combo of flounder and gimbap (seaweed rice roll) would taste like, and I loved being able to enjoy sashimi and rice together — the flounder felt different eaten alone versus with the rice, so it was fun to mix it up depending on the mood! ![A single piece of flounder salt gimbap](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-12-1g1hw-900.webp) ![Gimbap combined with flounder, aged kimchi and Maldon salt](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-13-ot168-900.webp) Gimbap + flounder + rinsed aged kimchi + Maldon salt combo 🤍 The clean flounder, savory gimbap, tangy rinsed aged kimchi, and Maldon salt all came together really well! The flounder's clean flavor plus the kimchi's bright tang plus the subtle salty edge from the Maldon salt made for real umami...👍🏻 ![Close-up of gimbap topped with flounder and aged kimchi](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-14-1wt7t-900.webp) ![Chewy flounder fin sashimi](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-15-42op4-900.webp) The gimbap portion was generous too, so it was easy to keep pairing it with the flounder. Clean and salty with the tangy kick from the aged kimchi made it taste better than eating either alone haha The flounder fin had such a chewy texture that it felt like a waste to eat with gimbap, so I just ate it plain lol the fin is my absolute favorite part..🫶🏻 ![Chicken nanban topped with tartar sauce](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-16-15n2y-900.webp) ### Chicken nanban piled with tartar sauce Chicken nanban, Japanese-style fried chicken, came out with crispy fried chicken piled high with tartar sauce! There were also fried peppers alongside the chicken, which I loved haha ![Plate of chicken nanban with fried chicken and fried peppers](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-17-1kyg2-900.webp) ![Cross-section of bite-sized chicken nanban](https://img.superchart.com/images/sinnonhyeon-izakaya-goko-chicken-nanban-highball/sinnonhyeon-izakaya-goko-chicken-nanban-highball-18-1hgy3-900.webp) One bite and you could really feel the crispy outside, tender inside texture of the chicken, and since it's fried, it paired perfectly with the highball! Enjoying the clean flavor of the flounder and finishing off with the chicken nanban left me full and satisfied :) If you're looking for an izakaya near Gangnam Station with great food and a great vibe, I'd recommend Izakaya Goko 🪽 ## Where it is - Izakaya Goko Gangnam Sinnonhyeon Branch (이자카야 고코 강남신논현점) - 21 Bongeunsa-ro 2-gil, Gangnam-gu, Seoul, South Korea (반석빌딩 2층) - 서울특별시 강남구 봉은사로2길 21 반석빌딩 2층 이자카야고코 - 37.5033195, 127.0261503 - Google Maps: https://www.google.com/maps/search/%EC%9D%B4%EC%9E%90%EC%B9%B4%EC%95%BC%20%EA%B3%A0%EC%BD%94%20%EA%B0%95%EB%82%A8%EC%8B%A0%EB%85%BC%ED%98%84%EC%A0%90/@37.5033195,127.0261503,17z --- Superchart · https://superchart.com/en/@eulji-neon-glass/sinnonhyeon-izakaya-goko-chicken-nanban-highball/ · https://superchart.com/llms.txt
