Sukhumvit runs the length of central Bangkok along the BTS line, a chain of numbered sois that holds most of the city's after-dark energy. The list below covers the rooms our editors return to, from a hidden speakeasy on Soi 21 to a canopy rooftop and a record-shop bar. Compare them with our best cocktail bars in Bangkok and the full Bangkok bar guide.
Sukhumvit Soi 21 · $$$
Q&A Bar sits down a quiet stretch of Sukhumvit Soi 21 as a narrow Art Deco room styled like a train carriage. The bartenders work a classics-led list with table service along the bar. It has appeared on the Asia's 50 Best Bars list.
Sukhumvit Soi 11 · $$$
Havana Social hides behind a phone booth on Sukhumvit Soi 11 with a pre-revolution Cuban theme. Rum and cigars drive the program and a live band plays most nights. The room runs late and fills on weekends.
Sukhumvit Soi 11 · $$$
Above Eleven crowns Fraser Suites on Soi 11 with a New York park theme and a Nikkei kitchen. The open-air deck looks over the Sukhumvit skyline. Come early to beat the dinner rush for a rail seat.
Sukhumvit Soi 40 · $$$
Tichuca Rooftop tops the T-One building on Soi 40 with a glowing tree-like canopy bar. The 46th floor draws a young crowd for cocktails and DJ sets. Lines build after sunset, so book a table to skip the wait.
Sukhumvit Soi 45 · $$$
Sing Sing Theater turns Soi 45 into a 1930s Shanghai fantasy of red lanterns and caged balconies. The room mixes cocktails with cabaret and late dancing. It leans theatrical and runs deep into the night.
Sukhumvit Soi 51 · $$
Studio Lam comes from the Zudrangma Records team on Soi 51 and plays molam and global grooves on a custom sound system. The bar serves Thai-spirit cocktails and herbal infusions. Live sets fill the floor on weekends.
Sukhumvit Soi 51 · $$
WTF Bar joins a cocktail bar to an art gallery on Soi 51 in a restored shophouse. The drinks list mixes Thai ingredients into classics and the walls rotate local shows. It stays small and draws a creative crowd.
