ONYX BANGKOK
RCA Alley, Bang Kapi, Huai Khwang, Bangkok 10310
Come for the international headliners. ONYX has hosted ZEDD, The Chainsmokers, Steve Aoki, and Showtek on the MainStage, while Odyssey handles the closer sets. If you want stadium-scale production without leaving Bangkok, this is the room.
You walk into the MainStage room and the balconies ring the floor like an arena. The capacity pushes 1,800 to 2,000 depending on the night, and the D&B Audiotechnik rig is built to fill every corner without distortion. ONYX runs a two-room layout: the MainStage handles the headline acts and the big-budget production, while Odyssey operates as a second, smaller space with a different energy.
The music programming leans into EDM, trap, electro-house, and hardstyle. Past lineups have included The Chainsmokers, ZEDD, Steve Aoki, 3LAU, Fedde Le Grand, Headhunterz, Bingo Players, Dannic, Alan Walker, and Andrew Rayel. The club opens at 9:30 PM and runs until 4 AM every night of the week, which gives it a consistency rare for venue-driven bookings at this scale.
RCA is a dedicated nightlife strip. Parking exists but the soi compresses on weekends, so ride-share drop-off near the RCA entrance is often faster than circling for a spot. The club accepts reservations by phone and offers table service with full bottle options across beer, wine, spirits, and cocktails. There is outdoor seating, though most of the action stays inside where the sound system matters.
ONYX ranked 74th in DJ Mag's Top 100 Clubs poll for 2021, the second-highest Thai venue on that list. The ranking reflects booking consistency and production values, not just crowd size. Dress code enforcement tightens on Friday and Saturday nights. Call ahead if your group is larger than six.
