Havana Social is a retro Cuban cocktail bar on Sukhumvit that runs regular Latin nights; vintage décor, warm lighting and a long bar set the scene for partner dancing between tables. It’s open every night from 18:00–02:00, so you can come early for drinks or arrive late for the music.
Sunday is the main social night, DJs spin bachata-heavy sets with salsa mixed in. Entry is usually free (several reviews note a 400‑THB cover on some nights) and drink prices are high compared with other Bangkok bars (roughly 360–4,100 THB), so budget accordingly. Expect the dance area to get going after about 21:00–22:00, with a mix of local Latin-music fans and expats.
This is a cocktail-bar layout rather than a big dance hall: couples weave between tables and ordering at the bar can be chaotic when busy. The music programme can drift (some guests report R&B between Latin sets), so check the night's lineup if you’re coming specifically to dance.
