#FindTheLockerRoom

Five of Asia's best-known bartenders, Hidetsugu Ueno of Tokyo's Bar High Five, Colin Chia of Singapore's Nutmeg & Clove, Nick Wu of Taipei's East End, and Bangkok's Ronnaporn "Neung" Kanivichaporn and Chennarong Bhumichitr, opened one shared 35-seat bar behind a wall of steel gym lockers in Thonglor in 2017.

Why go

The menu is the partnership made visible, split into Past, Present, and Future: Ueno handles faithful renditions of the classics, Wu and Chia modernize them, and the Future section runs experiments like the Bloodless Maria, which per 50 Best Discovery uses mezcal instead of vodka and incorporating tomato sous-vide. Time Out called the opening possibly the most groundbreaking bar opening in Bangkok in 2017 and, nine years later, still lists it among the city's best speakeasies as the OG of the Bangkok speakeasy scene. The same crew runs #FindThePhotoBooth nearby.

Order this / avoid

  • Order: one drink from each era, in order; the point is tasting three generations of technique argue with each other. Start Past with an Ueno classic, end Future with the Bloodless Maria.
  • Avoid: hunting for a sign; there is none. The entry is the ritual: find the right locker in the bank of steel lockers off the alley at 406 Sukhumvit 55 and slide it open.

What locals & experts say

  • Time Out Bangkok: possibly the most groundbreaking bar opening in Bangkok in 2017, a room that still feels alive and still feels earned.1
  • Time Out Bangkok (June 2026): on the current best-speakeasies list as five of Asia's foremost bartenders, each with their own acclaimed venue in a different city, joining forces to open a single collaborative speakeasy in Bangkok.2
  • Asia's 50 Best Bars (extended list): No. 78 in both 2022 and 2023, per Time Out Bangkok.4

Good to know

  • Timing: daily, 7pm to 2am per Time Out's listing.
  • Booking: effectively walk-in; 35 seats, so weekends fill. A DM ahead is the safe play, though the reservation channel is unverified.
  • Getting there: off Thonglor at Sukhumvit 55; short ride from BTS Thong Lo, and an easy pairing with the Thonglor cocktail cluster (Dry Wave, Thaipioka) in one night.

Verdict

should-visit — A format that exists nowhere else in Bangkok: five of Asia's name bartenders, Ueno of Bar High Five among them, each authoring a section of one menu behind a wall of gym lockers. Nine years in, Time Out still lists it among the city's best speakeasies and calls it the scene's OG. Extended-list ranks rather than top-50 hardware keep it a detour rather than a pilgrimage.

Order

  • One drink from each menu era: Past (Ueno's faithful classics), Present, Future
  • Bloodless Maria (mezcal, sous-vide tomato) from the Future section

At a glance

  • Booking: walk-in
  • Timing: open late
  • Best for: drinks, date, solo, groups ok
