Alonetogether Bar Bangkok

The teams behind Ku Bar and Sugar Ray merged crews in 2019 to open a two-story shophouse jazz room on Sukhumvit 31, named for the Chet Baker standard and stocked with a record store and cigar lounge upstairs.

Why go

Anupas Kong Premanuwat, the Angel's Share-trained bartender from Ku Bar, runs the stick, and per 50 Best Discovery he switches up modern classics by swapping mainstay ingredients for local alternatives: a China Blue on fresh wasabi, a Screwdriver rebuilt as a pomelo slushie. Coconuts clocked the opening lineup at B380-420, Hot White Russian on homemade coffee liqueur and soy cream included, with live jazz four nights a week from The Pomelo Town and Podchara Quartet. The bar was designed around drinking alone well, which is the joke in the name.

Order this / avoid

  • Order: the Cold Fashioned (bourbon, bitters, black cardamom, raw cane sugar) or whatever local swap Kong is running; the Frozen Screwdriver is the summer call.
  • Avoid: showing up for silence. When the band plays, the downstairs bar is the music room; the upstairs lounge with the records and cigars is the quiet option.

What locals & experts say

  • Coconuts Bangkok (2019): on the solo-drinking premise, This ultra-chill new space may just change your mind.1
  • 50 Best Discovery: great drinks and top-notch service, with a little live jazz on the side.2

Good to know

  • Timing: daily, evenings to about 2am; sets start mid-evening.
  • Booking: walk-in scale; a DM ahead is sensible on live-music nights. Aggregator chatter mentions a solo minimum spend, which no critic or guide confirms, so budget with that possibility in mind.
  • Getting there: Soi Sukhumvit 31, between BTS Phrom Phong and Asok, an easy add-on to a Sukhumvit dinner.

Verdict

could-visit — Solid and specific: the Ku Bar and Sugar Ray teams' shared living room, where an Angel's Share-trained bartender swaps classics onto Thai ingredients while live jazz runs four nights a week. Nothing here carries award weight, and the evidence is listing-grade, so it stays a could-visit, the right bar when you are near Phrom Phong and want drinks with a rhythm section rather than a pilgrimage.

Order

  • Frozen Screwdriver (pomelo blended to a slushie)
  • Cold Fashioned (bourbon, bitters, black cardamom, raw cane sugar)
  • China Blue with fresh wasabi
  • Live jazz sets from The Pomelo Town and Podchara Quartet
