La Contraseña Restaurant

"This modern little spot in the Chamberí district is famous for its excellent cocktails (locals go for the gin and tonics in particular), which are best enjoyed in the bar near the back of the restaurant. If you're stopping in for a full dinner, request a seat on the open-air patio, which is surrounded by exposed brick walls. The stunning décor—think wicker basket chandeliers, graphic printed wallpaper, a mirrored bar, and colorful tile—is reason enough to make a reservation. "
