Pizzeria Bianco. Called the world's best pizza, by many an experienced critic. This one well known bread chef, Peter Reinhart, went all over the world (New York, Chicago, Naples, Florence, Greece) in his hunt for the perfect pie. He found it here, in Phoenix. Perfect place, I think. Only downside is that they open at 5, and do NOT take reservations. Get there at 3 or 3:30, if you want seats. I'd go for 3 on a weekend. The prices are reasonable. Around 12-15 a pie. Problem is, the crust is not a traditional crust, and I wager I could eat 2 of those pizzas no problem. Not so filling. They have a bar/winery next door that opens at 4, same owner. Good chance to get to know her, and the pizzas are, in fact, the worlds best. Look it up, its like 50 yards from the Science Center Downtown. Worth the drive, worth the wait. Best meal I have ever had, and for a kid, I have some serious standards. Best part is, the guy, Chris Bianco, is there every single night. I even touched him. Chris Bianco > God
Seriously, don't dismiss this cause of my age.
EDIT: Its pretty casual around there. Put on a nice pair of jeans, or some khakis, a good looking t-shirt, or a polo, or a decent camp shirt. You won't be out of place.
