It's pretty tasty stuff! They offer some interesting pizzas and the ingredients are usually pretty fresh. Sometimes if you go in at kind of a slow hour and get a slice, it'll be a little on the 'meh' side. The calzones are pretty good, they'll fill the craving if you have one.
Honestly what I am a big fan of at zPizza is their sandwiches and salads. They're flavorful, fresh, and the bread is awesome. The salads have interesting combinations and are a nice size.
Hit Pink Spot next door afterward for maximum gluttony.
