Fodor's Expert Review El Mosquito

Signed photos from the likes of King Juan Carlos and Julio Iglesias cover the walls of this elegant stone-wall restaurant opened in 1928. Specialties include lenguado a la plancha (grilled sole) and navajas (razor clams). The tocinillo de cielo, a double-rich caramel flan, is heavenly, as the name implies. The restaurant's name refers to an era when wine arrived in wooden barrels: if mosquitoes gathered at the barrel's mouth, it held good wine.
