Established in the 1920s, La Plata is one of a trio of famous bodegas on this narrow medieval street. This one occupies a corner building -- whose two open sides allow aromatic cooking odors to permeate the neighborhood -- and contains a marble-topped bar and overcrowded tables. The culinary specialty comprises raciones (small plates) of deep-fried sardines -- head and all. You can make a meal with two servings coupled with the house's tomato, onion, and fresh anchovy salad. The highly quaffable Penedés house wine comes in three varieties, tinto, blanco, and rosado.
