This street houses over a dozen tapas restaurants and bars, just within a block or two. It is right next to Plaza Mayor, very easy to get to and close to the center of the city. The area's tapas places are frequented by tourists and locals alike. We found ourselves in La Tempranilla, which I reviewed on TA, and both the food and wine there were excellent. Little or no English was spoken, although there were menus in English available, and there were mostly locals there at the bar while we were eating, so it was not primarily aimed at tourists. As with many Spanish eating establishments, opening times are usually 8-8:30 and the action often doesn't pick up until substantially later.There were a handful of places that were open before 8, and these were geared towards tourists. We were not out past 10 but I'm sure the street must get very lively later in the evening!
