Arzak is Basque avant-garde with family at its core. Juan Mari and Elena Arzak's restaurant helped teach the world that San Sebastián's culinary tradition could be experimental without losing its appetite. The food can be playful, colorful and highly technical, but it remains grounded in Basque flavors, local seafood and a restless test-kitchen spirit. It is not the newest rebel on the block anymore, and that is part of its charm: a revolutionary house that has become a living institution.
