This upscale cocktail bar in downtown Boston was inspired by the glamour and ease of 1950s Havana, and designed as a relaxed alternative to nightclub culture. The subterranean lounge pairs low lighting, plush seating and art deco touches with a drinks program centered on martinis, house‑made ingredients and polished classics. A small menu of shareable plates and a rotating lineup of live music and DJs reinforce its positioning as a grown‑up, after‑dinner destination.
