First of all, NO, these are not the secret recipes of Giordano's, Gino's, Pizzeria Uno, or the others.
They are, however, very good pizza recipes. My main criticism of the book is that some of the instructions are incomplete. For example, in the stuffed pizza recipe he tells you to put the sauce on top of the pizza without pre-cooking the pizza at all. In my experience, that always results in a doughy, partially-uncooked top crust. I prebake the pizza with no sauce for about 10 minutes, then add the sauce, and it's great. But Bruno should've told me that; I shouldn't have had to figure it out for myself.
Yes, I would like to get my hands on the actual Giordano's recipe, but these recipes still beat any pizza I can get here in Oregon.
