21Gam occupies a century-old French colonial building in Hanoi's Old Quarter, featuring one of the city's longest bars crafted from reclaimed ship planks and hand-made terrazzo. Opened in 2020, the dimly-lit space exudes mystery with an orange-hued ambiance, enhanced by an oversized moon suspended from high ceilings. A thoughtful DJ complements the intimate setting without overwhelming conversation. Cocktails range from 200,000–300,000 VND, with custom creations available. English-speaking bartenders provide entertaining service in this youthful yet sophisticated venue that captures Hanoi's evolving cocktail culture.
