40 Thieves hides up an unsigned stairway at Jl. Petitenget No.7 in Seminyak, directly above the Japanese ramen shop Mad Ronin. There is no sign at all, and the house advice stands, if you get lost, ask at the ramen counter.
Bar entrepreneur Shah Dillon runs the room as one part New York speakeasy, one part dive bar. Lonely Planet describes the grungy industrial styling, old maps and vintage bicycles included, and the crowd mixes expats, locals and travelers who did their homework.
The list holds exactly eight cocktails by design, less flipping, more mingling, and Difford's Guide lists the room among Bali's serious cocktail addresses. The bartenders build off menu requests without ceremony.
The Honeycombers flags the happy hour as one of Seminyak's better deals, and the standing room fills from 10pm. Recent coverage reports the bar has been working on a relocation, so check its pages before a special trip.
Climb the stairs early for a counter seat and start with the list's first page. For more hidden doors, see our Bali hidden gems guide, the best cocktail bars in Bali, and the near me bar finder.
The 8pm open through 10pm is the conversational window with counter seats free, and the happy hour lands in it.
