From what I understand, Giovanni's is a Northern US chain. I live in South Carolina so my first experience with it was when I when to Greenup county, KY to visit my in-laws.
My wife grew up on it but I tried it for the first time over the Christmas weekend for lunch. They had a buffet and when they brought out the fresh pizza's they were very good.
It was thin crust but not cracker style. It seemed thinner than NY style though.
Sauce was good but not overpowering. More balanced.
Cheese melted like and tasted like whole milk mozzarella.
All in all a very good experience and would recommend it.
