This justly popular restaurant is housed in an 1860s building that also incorporates an 11th-century Moorish well. Time may have stood still with the setting, but the cuisine reflects a modern twist on traditional dishes, including seafood mains like merluza en papillote con almejas y gambas (hake with clams and shrimp, cooked in parchment) or carpaccio de champiñón a lo Idiazábal (mushroom "carpaccio" with Idiazabal, a traditional Basque cheese). There's
also a reasonably priced and generous tasting menu (€35), and the wine and gin lists are among the best in the city. The restaurant is fronted by a popular tapas bar (€2.50 including drink) that is generally filled with a boisterous business crowd.
