Tiny and usually full, in the heart of Soho, this was a meeting place for the French Resistance during World War II before becoming a home to artistic and literary London—it's famously the place where an inebriated Dylan Thomas accidently left his manuscript for Under Milkwood. Truly one of a kind. Beer is sold only in half-pints. 49 Dean St. (Tube station: Tottenham Court Road), London W1. Phone 020-7437-2799.
