Castor Club

Cocktail Bar in St-Germain & Les Invalides

Discreetly signed, this superb underground cocktail bar has an intimate English gentleman's club–style upstairs bar with vintage wall lamps and slinky, red velour stools. But it's downstairs, in the 18th-century stone cellar with hole-in-the-wall booths, that the real cocktail-sipping action happens. Blues tracks add to the already cool vibe.
