I'm from Chicago and one of my friends moved to Scottsdale and recommended this place as something equivalent to our 3rd best deep dish in Chicago but the best available in the Phoenix area. He was spot on.
The pizza is pretty good, it is the best you can get without having the cool specialties like butter crust or slab sausage that covers the whole pizza. But definitely try the Vito specialty Deep Dish, it is good pizza and I would go back for sure :) The service is good as well and it has a very homely feel to it :)
I wanted to try the tiramisu but was so stuffed after my one piece of the large (which fed 4 of us with 4 slices left over, mmm) I did have a piece of pizza bread and a sliver of fried zucchini though, both of which were pretty good.
