Run by a couple, this popular tavern -- highly praised by local restaurant owners and restaurant goers -- is something between a tapas bar and a restaurant. It has three small dining areas, floor and walls of red Italian marble, plain wooden furniture, and a menu that is representative of Basque cuisine. Try any of the fish or mushroom revueltos (scrambled eggs), the habas (broad beans), or the bacalao (cod). And order a glass of txakolí (tart, young Basque white wine). Reservations essential.
