Bangkok's hotel bars run from the banks of the Chao Phraya to rooms thirty floors up. The best hotel bars in Bangkok start on the river at BKK Social Club in the Four Seasons, No. 30 in the 2026 edition of The 50 Best Bars and the 2024 Spirited Awards' Best International Hotel Bar, and The Bamboo Bar at the Mandarin Oriental, which opened in 1947 as the city's first jazz venue. On the 30th floor of Rosewood Bangkok, Lennon's is reached through a record shop and sits at No. 7 on Asia's 50 Best Bars 2026. Aqua Bar fills a garden at the Anantara Siam. The Bamboo Bar takes no reservations. These are the eight we would start with.

Latin American glamour meets Thai hospitality at the Four Seasons on the Chao Phraya, under beverage manager Philip Bischoff (ex-Manhattan, Singapore).

Director of bars KT Lam (ex-DarkSide Hong Kong) and bar manager Kosil 'James' Kamja pour the 'Bangkok Beats' menu, eight Thai flavors as musical movements, beside rare spirits back to the 1970s.

From its modest start in 1947, The Bamboo Bar has grown into a Bangkok institution, the city's first jazz venue, still wrapped in its sensual 1950s ambience at the Mandarin Oriental. Live jazz plays nightly with band and vocalist, and the current 'Evolution' menu draws on the natural progression of bamboo and local Thai ingredients. Elegant attire after 6:30pm; no reservations, a sought-after walk-in. It received the Timeless International Award at the 2026 Tales of the Cocktail Spirited Awards.

A garden bar within the Anantara Siam Bangkok, set beside the hotel's Parichart Court with a koi pond and terrace seating.

The glittering heart of the Sindhorn Kempinski: deep armchairs and dark wood offset by moss-green panelling, nightly live jazz, and a Casa Del Habano cigar parlour.

The Loft sits on level 56 of Waldorf Astoria Bangkok and is styled as a glamorous vintage New York artist's studio. Art deco meets art nouveau around a bronze spiral staircase, with paint-splashed communal wooden tables and a floor-to-ceiling glass wall over the skyline. The cocktails draw on historic recipes from the Old Waldorf Bar in New York and The Waldorf Astoria Bar Book, reworked with house-made ingredients: the Waldorf pairs Michter's bourbon with Thai basil and chocolate bitters, and the Illusion adds homemade pandan soda. Bar bites are served, and tables are booked through SevenRooms. Forbes Travel Guide named it a Star Bar for 2025. It was No. 88 on the Asia's 50 Best Bars 51-100 list in 2022.
