From the same owners as Michelin-starred Club Gascon, basement-level Le Cercle serves modern French cuisine in tapas-size portions. Sheer, floor-length draperies add privacy to the booth seating and elegance to the main dining room. In the lounge, padded ottomans and a fireplace create a cozy nook to sip on cocktails. The menu includes options like wild mushroom fricassee and squid ragout with crab bisque. Le Cercle is near Sloane Square, close to Cadogan Hall and the Royal Court Theatre and offers pre-theater menus.
