Casa Revuelta puts out some of Madrid’s finest tapas of bacalao (cod) bar none – unlike elsewhere, tajadas de bacalao don't have bones in them and slide down the throat with the greatest of ease. Early on a Sunday afternoon, as the Rastro crowd gathers here, it’s filled to the rafters.

It’s also famous for its callos (tripe), torreznos (bacon bits) and albóndigas (meatballs).
