1. BUOY (부우이 성수) Seongsu
Sunlight glints off olive oil, plates come out in calm colors, and the room smells faintly of seared beef and herbs—BUOY feels like a seaside detour in the middle of Seongsu. Loved by locals and visitors alike, the cooking is clean and generous, with a flank steak that sells out fast and pastas that keep a gentle, briny perfume to the last bite.
- Order this: Limited flank steak (reserve to avoid sellouts) and a bright, lemon-forward pasta to share.
