Bodega de la Ardosa

Tucked away on the cusp of Calle de Ponzano, Madrid's (and Chamberí's) most happening bar and tapas street, this fine relic and local institution serves some of the best patatas bravas (fried potatoes with spicy tomato sauce) in town. There's also vermouth on tap, and an extravagantly tiled facade complete with shrapnel holes dating back to the Spanish Civil War.
