About
Jazz bar in Gangnam with live nightly performances, wine list, and dinner menu. Popular for dates and small groups.
Flatnine runs Gangnam jazz with box-office discipline: nightly live sets at 8 and 10pm (hour-long, 20-minute intermission), CatchTable reservations booking out four-plus days for popular lineups (10K deposits auto-refund after the first set), and a seating hierarchy that matters — reserved guests take the front two-tops, walk-ins stand or bar-sit in back. The economics are structured: weekend bottle minimums (Friday-Sunday), weekday one-drink floors, 10K performance fees at settlement, and 15K breakage tariffs keeping the glassware honest. The wine list and dinner menu run date-grade; the Instagram carries artist lineups worth pre-checking. Weekend matinee hours (3pm Saturday-Sunday) add afternoon sets. Gangnam's jazz tier is thin; Flatnine's nightly commitment — two sets, real bookings, enforced attention — is the district's standing chart.
