I would understand the skepticism from those who might say "Really? The 'Best Pizza in the World' is in Phoenix?" Well, I haven't been around the world, so I can't say, but what I CAN say is that the pizza at Pizzeria Bianco is outstanding. My brother just visited but was only here on a Sunday, and he was very upset they weren't open because he had been looking forward to returning for months! It's usually pretty busy - you might get lucky and be seated immediately, but be prepared to wait. I've tried four of their pizzas and they are all outstanding. The dough is probably the best I've ever had, the combination of flavors is simple and powerful, the sausage is exquisite (made specifically for the restaurant), and the prices are outstanding for the quality of the food. It's a place that I will treasure taking visitors, very conveniently located downtown (though parking can be tough in the small lot immediately adjacent). Best in the world? Possibly - certainly worth deciding for yourself!
