Most are archetypal neighbourhood cervecerías, unchanged since the Franco era. El Doble, at number 58, is a classic castizo-style corner bar known for cañas (draft beer in short, cold glasses) and conservas (canned seafood like sardines and mussels, eaten straight from the tin with toothpicks). But #ponzaning only started trending because of Sala de Despiece, or “the cutting room”, a much newer institution at number 11.
