Castor Club

A genuinely hidden Saint-Germain cocktail bar — look for the small door near rue Saint-André des Arts — where the wood-panelled interior channels an American lodge rather than Parisian elegance. Whiskey and brown spirits shine here; tell them your preferences and let them work. Come late, when the lodge atmosphere peaks, once you've found the door. It is the antithesis of the polished Parisian cocktail room — warm, woody, and serious about its spirits, a secret worth the hunt. The contrast between the Left Bank address and the cabin-like interior is the whole charm, and the drinks reward the effort of finding it.
