I really only know pizza places on the Northeast. When I am in other parts of the country I don't try it. Even though Bon Appetit said that Bianco's in Phoenix is the best pie in the country. Would like to try some chicago style in Chitown, but this is what I know.
Difara's, Avenue J the key is just to be the first one there and anything that comes out of the oven, just take it. A sublime experience
Grimaldi's under the Brooklyn Bridge. Extraordinary as well but for whatever reason it tasted better when it was named Patsy's.
DeLorenzo's Chambersburg, Trenton NJ I love Hudson and Robbinsville, but I think Robbinsville is better because all of the pizzaiolis are all at the Robbinsville location
DeLorenzo's Hamilton- More Tomato Pies. Another wing of the family and incredible too, very friendly atmosphere
Nunzio's Staten Island. I think I like this more than Joe and Pat's, I love the sauce at Nunzio's. However, I heard it was recently sold and not as good, does anyone know this is true. They certainly renovated, I loved it more when it was a true hole in the wall.
Totonno's.- I rarely get the chance to go here, but I love it, its off the cuff pizza making, no round pies here.
Spumoni Gardens, Brooklyn, for Sicilian of course!
