NOTE * Heat Up Pizza is a new way of enjoying your pizza. Our pizzas are fully cooked in wood fire ovens then chilled and sold cold so you can have the option to heat up and enjoy your pizza at your convenience. ** Heating instructions are labeled on all our pizza boxes to achieve pizzeria quality results every time. *** All pizzas are made with Di Cartio's 12-hour slow simmered aromatic tomato sauce and five cheese special blend.
