After having eaten Pizza at the most heralded Pizza joints in the US: A16 (San Francisco), Serious Pie (Seattle) - (see the recent Wine Spectator- June 2008). I'd have to say that Pizzeria Bianco is the winner. But, only barely. The Bianco Pizza was more consistent all the way through. The A16 pizza last time I had it was a little soggy in comparison the Biancos.
We didn't do anything correctly for showing up at Biancos. We showed up at 8pm. And, waited for a table for 2.5 hours. It worked out well, because we just went next door and had a few glasses of wine before dinner. This worked out well and waiting isn't a problem (as long as you're with cool people).
The wait was surely worth it. Bianco only serves 6 pizzas. Only 2 with red sauce. But, the ingridents used were probably the most selective in Arizona. Think Thomas Keller particularism in Arizona. And, that's very difficult to do in Arizona - b/c the ingredients here inherently suck.
