Ricardo Gil and María Pilar Vicente, owners of the Treintaitres restaurant, every day prepare the ingredients in their own culinary style, which includes attention to detail, non-conformity and a commitment to local products; a project which started in 1952. The undisputed protagonists of the restaurant are the vegetables from the Tudela's fertile zone, which they grow themselves, whose full flavours they extract while observing their natural qualities. Their entrepreneurial spirit and desire to publicise their work are reflected in another 2 parallel establishments: Casa Lac in Zaragoza and La huerta de Tudela Green and More in Madrid.
