By far the best pizza I've ever had. I've never been to Pizzeria Bianco in Downtown Phoenix, but I have friends who've been to both and say the Pomo is much better. My favorite is the Principe Pizza and the Buffalo Mozzarella Pizza. I usually go their with my girlfriend and we split a salad and pizza, but if you're hungry a single pizza can be easily finished by one person. They have a wonderful wine selection as well.
What really sets this place apart from others is it is the only Naples Certified Restaurant in Phoenix. This means that all of their ingredients are organically grown in Naples. I recommend making reservations as they fill up quickly, however they almost always have outside seating.
