This family-owned small chain of Pizza joints is my favorite place in Arizona to get a pie. I have never ventured to Pizza Bianchi, partly because I am told that there is an hour and a half wait, and really, who has an hour and a half to wait outside in Phoenix for pizza? I have been to Grimaldi's. Grimaldis was very adequate.
Nellos is extravagant pizza! They make their own sausage in house. Chicago style. They have Sicillian style too, but I avoid it and opt for a thin crust. I have had a few salads at Nellos and both were ample and delicious. This place seems like a good place to watch a game or have a pint as well, with plenty of good beer on tap.
One of the owners is a local artist so there are plenty of fun things to look at even if you aren't watching a D-Backs game.
I like the atmosphere at the Gilbert restaurant the best. The outdoor patio is great, but the artist/owner runs the Scottsdale location.
