Casa to tu! "To tu!" means "it's here!" but this casa can be easy to miss: the slightly uninviting entrance is through a courtyard and down steps to a cellar door; you'll see a sign. But once you find the restaurant, you'll be glad for the effort. The gazpacho, paella, and tapas are all excellent, and the setting very pleasant: calming ambient lighting, warm colors, and wood tables and chairs give the space a comfortable, cozy feel. Plus the service is as good as the prices are reasonable.
