# Seongsu gyukatsu restaurant, weekend lunch with ramune: Gyuen Dang - By Yoonseo Baik (https://superchart.com/en/@nakwon-back-table/) - Written Sep 18, 2026 - Local places › Restaurants › Seongdong, Seoul - Sponsored: This story was written following a sponsored restaurant visit. - English edition: https://superchart.com/en/@nakwon-back-table/gyuendang-seongsu-weekend-lunch-ramune/ - Also in: [한국어](https://superchart.com/ko/@nakwon-back-table/gyuendang-seongsu-weekend-lunch-ramune/index.md) ## In short Gyuen Dang Seongsu Main Branch is a gyukatsu (beef cutlet) and Japanese home-style restaurant on the second floor of a building in the alley by Seongsu Station exits 3 and 4 in Seongdong, Seoul. Booked on Naver for weekend lunch, the meal was striploin gyukatsu, hamburg omelet rice and ramune soda, with each slice seared just 15 to 20 seconds a side on a tabletop grill so nothing came out tough. Gyuen Dang tasted better than Motomura Gyukatsu in Fukuoka, so reserve before you go. ## Good to know - **Location**: Inside the alley from Seongsu Station exits 3 and 4, second floor of the Gasit building next to Betong - **Reservations**: Available through Naver or Catch Table; groups of 6 or more are hard to book - **Seating**: Bar-style seats and face-to-face tables; the room is on the small side - **Dishes ordered**: Striploin gyukatsu, hamburg omelet rice, ramune soda - **Perk**: Mini okonomiyaki for writing a review *as written by the visitor on Sep 18, 2026* I remembered the gyukatsu I had in Fukuoka, Japan last year and went looking for a good gyukatsu spot in Seongsu — and stumbled onto Gyuen Dang Seongsu Main Branch (규엔당 성수본점) 🥩🔥 💬 By the way, gyukatsu apparently comes from combining 'gyu (牛)', meaning beef, with the Japanese pronunciation of 'cutlet' (katsu, カツ)! ## Where is Gyuen Dang Seongsu Main Branch, and how do you walk there from Seongsu Station? ![Exterior of the Seongsu-dong alley building where Gyuen Dang Seongsu Main Branch is located](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-01-fgdrp-900.webp) ![2nd floor entrance of Gyuen Dang Seongsu Main Branch near Seongsu Station](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-02-17f1t-900.webp) Come out of Seongsu Station exit 3 or 4 and head into the alley — Gyuen Dang Seongsu Main Branch is on the 2nd floor of the building next to Betong 📍 Seongsu is packed on weekends, so hot right now, tons of foreign visitors too 👥 ![Stairway up to the 2nd floor with the Gyuen Dang Seongsu Main Branch sign](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-03-1vy99-900.webp) ![Entrance of Gyuen Dang Seongsu Main Branch with a weekend lunch waiting line](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-04-1lymk-900.webp) ## Weekend lunch at Gyuen Dang: how long is the wait, and how do you book? Gyuen Dang Seongsu Main Branch already had a wait when I showed up for weekend lunch 〰️ ⏳ Good thing I'd booked ahead on Naver. You can also reserve through Catch Table, so ⭐️ definitely book before you go ⭐️ ![Compact interior of Gyuen Dang Seongsu Main Branch with bar-style seating](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-05-18eow-900.webp) ### Seating at Gyuen Dang and whether groups fit The restaurant itself is smaller than I expected, so I heard parties of 6 or more have a hard time getting a reservation — keep that in mind 🪄 Seating is a mix of bar-style seats and face-to-face tables 🪑 ![Gyuen Dang menu listing gyukatsu, rice bowls, and omelet rice](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-06-oa2e8-900.webp) ## What's on the Gyuen Dang menu? Besides the signature gyukatsu, the menu ranges across Japanese home-style dishes too — rice bowls, omelet rice, curry, udon 🍛🥢 Also, if you write a review, you get a mini okonomiyaki on the house 🎁 ## What we ordered at Gyuen Dang ![Full striploin gyukatsu meal set ordered at Gyuen Dang Seongsu Main Branch](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-07-19116-1200.webp) ![Gyukatsu, omelet rice, and ramune soda laid out on the table](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-08-1c8yd-900.webp) I stuck mostly to the recommended and signature items on the menu! 📝 They also had ramune soda, so full-on Japanese vibes, so I had to try it — there's a marble stuck in the neck of the glass bottle, and it tastes exactly like the carbonated version of a Bbongtta popsicle 🩵🫧 ![Ramune soda bottle with a marble in its neck](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-09-1hny5-900.webp) ## The striploin gyukatsu set and how to grill it The striploin gyukatsu came out with rice, salad, miso soup, pickled radish, wasabi, salt, house sauce, and butter, all neatly arranged 🥩🍽️ - ❶ Grill two pieces of meat plain first, to taste the beef itself - ❷ Add a quarter pat of Isigny butter on the grill for extra richness - ❸ Dip in wasabi, then salt, then the house sauce, in that order ![Tabletop grill and gyukatsu spread with wasabi, salt, and house sauce](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-10-1tw6b-900.webp) ![Isigny butter served alongside gyukatsu dipping sauces](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-11-yy63o-900.webp) Following the eating instructions and tips on the table, I grilled the gyukatsu on the tabletop burner 🔥 ⭐️ 15-20 seconds per side on the cut face ⭐️ The key is not to fully cook the beef, just sear the surface!! ![Striploin gyukatsu being grilled front and back on the tabletop burner](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-12-1lac3-900.webp) ![Close-up of striploin gyukatsu seared only on the surface](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-13-yd030-900.webp) ![A piece of gyukatsu topped with pink salt and wasabi](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-14-iiycw-900.webp) Crispy on the outside, moist inside, and the beef wasn't tough at all — so tender 🥹👍 With a little pink salt and wasabi, you could really taste the flavor of the beef itself even more 〰️, and the house sauce had a sweetish soy-sauce vibe that gave it a whole different charm! ![Hamburg omelet rice at Gyuen Dang covered in an egg blanket](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-15-7p22c-900.webp) ![Plate of hamburg omelet rice with sauce poured over it](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-16-7i9e8-900.webp) ## Hamburg omelet rice at Gyuen Dang Hamburg omelet rice, with a juicy hamburg patty draped in a blanket of egg 🍳 A lot of other diners seemed to be getting the brie cheese omelet rice — I'll try that next time! ✊ - ❶ Cut into the egg so it can slowly spread open - ❷ Wait for the natural moment the egg opens up on its own - ❸ Pour the sauce so it cascades over, rather than smothering it ![Inside view of the hamburg omelet rice with the egg cut open](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-17-16xii-900.webp) ![A spoonful of moist egg and hamburg patty from the omelet rice](https://img.superchart.com/images/gyuendang-seongsu-weekend-lunch-ramune/gyuendang-seongsu-weekend-lunch-ramune-18-522l3-900.webp) My egg blanket didn't spread out prettily, but the combo of moist egg, juicy hamburg patty, and tangy sauce worked really well together! 💗 ## Gyuen Dang vs Motomura Gyukatsu in Fukuoka Gyuen Dang Seongsu Main Branch actually beat Motomura Gyukatsu, a fairly famous spot in Fukuoka, Japan, in terms of taste 🥩🔥 Beyond the gyukatsu, the menu's range of Japanese home-style dishes makes it a great spot in Seongsu when you're craving a tasty meal with Japanese vibes!
