Daenakk Sikdang Seongsu (대낚식당 성수)

Daenakk Sikdang (대낚식당) is a Korean restaurant on Yeonmujang-gil, the dining corridor that has come to define modern Seongsu. The name plays on the word for "fishing" (낚시), and the kitchen leans on that identity with a menu that puts fresh, seasonal ingredients front and center — Korean staples treated with the kind of care you would expect at a small neighborhood bistro rather than a fast-casual eatery. The space is small and cozy, with the kind of warm lighting and minimal-but-considered decor that has become a Seongsu signature, and the team takes hospitality seriously: expect attentive service, careful plating, and a quiet pride in the ingredients on each plate. The restaurant operates on a single-shift, all-day model from 11:30 to 22:00, which makes it easy to drop in for a late lunch or an early dinner without the booking-window stress that haunts many of its Yeonmujang-gil neighbors. The crowd skews local — Seongsu office workers at lunch, couples and small groups at night — and the vibe stays conversational throughout. With 252 Google reviews and a 4.8-star rating, Daenakk has built its reputation the slow way: quality ingredients, thoughtful preparation, and the kind of reliable warmth that keeps regulars coming back. For visitors looking for a less hyped, more grounded Seongsu meal, this is a strong pick.
