Probably the most modern in the barrio, this upscale Basque restaurant is all smooth wood, glass and brick, housed in a 19th-century building. With a very limited, simple menu, the main attraction here is the grilled steak ('chuletón de buey'), a contender for the city's best. Try the Idiazábal cheese, a speciality from the little Basque town of the same name. The maître d' will steer you through an excellent selection of more than 100 wines.
