A monument to pizza and Neapolitan recipes, it is now run by the fourth generation since it was set up by Don Umberto. Its lovely Thirties room, where mathematician Renato Caccioppoli, Bakunin’s grandson, used to gather together the finest minds in the mathematics institute of Naples, such as Cafiero, Greco and Stampacchia. Japanese emperor Akio Hito, Kennedy and Anthony Quinn all enjoyed its delights. It is the headquarters of the Umberto cultural and historic gourmet association for Neapolitan culture and cuisine.
