The menu includes a total of three pizzas which are all good: Margherita, Marinara and a white pizza. Stop. Frankly, this is more than enough. The rest of the success of Piz is due to the friendliness of the staff, from the colorful walls which pay homage to the art of Keith Haring, as well as a position which is more than central, a handful of steps from Piazza del Duomo. Reservations are not possible but for those who are forced to wait their turn for a seat consolation comes in the form of a glass of champagne and a taste of pizza. The most bearable wait their is.
