The decor of this restaurant in an ancient wine cellar could not be more fitting. The walls are covered with the ends of wine barrels that have been signed and decorated by contemporary Spanish artists. In 2009, new ownership injected fresh energy into this well-established and respected restaurant. The wines may be, as the name suggests, mostly from La Rioja, but the cuisine is Cantabrian through and through. You can count on some highly regional dishes, like mackerel dumplings and plates of meatballs surrounded by steamed clams and prawns. The kitchen goes the extra mile to make dishes special, even marinating fresh strawberries in Armagnac to serve with puff pastry for a simple seasonal dessert.
