This article floored me and motivated me to join the Forum.
I'm in the Land of Entrapment (NM). I'm lucky in that in the nearest city, ABQ, I found a real deli (Times Square Deli Mart--I will put the owner in my will) and a decent calzone. With some exceptions, I find pizza/Italian in the Southwest to be weak, with the caveat that I've never been to Phoenix. Tucson, I believe, may have best pizza East of the Mississippi.
Especially, I spend a lot of time in Vegas, and I really enjoy some of the pizza there (Settebello, Metro, Due Forni, Grimaldis). However, I doubt I would have put it in the top 10. Haivng a few good places does not equal East Coast saturation of quality pizza shops.
