Entry No. 21 — the Boston file — filed under: speakeasy

Backbar

An unmarked orange door in an alley between The Independent and Bronwyn is the only sign this 39-seat room exists — inside, co-owner Sam Treadway builds riffs on milk punch and pulls from unusual spirits, and there are no reservations: you walk in or you don't get in.

The move: Find the orange door with no sign in the Union Square alley, grab two of the 39 seats first-come-first-served, and split a round of Treadway's milk-punch variations.

Where: 7 Sanborn Ct, Somerville, MA 02143

Hours: Added 2026-07-20 — confirm current hours before you go.
