I agree with several comments. (1) You probably should have given Chicago its own list, since NYC got one. Providence deserves special mention for having a lot of great pizza too - glad you got one of their places on the list! (2) Pepe's in New Haven rocks! And don't miss the pic of President Reagan waving as he gets back in his limo after eating there. Classic. If you go, you need to understand that the 90 year old rude waitresses are part of the charm. (3) I'm now ridiculously hungry and leaving work early.
Also, thanks for the tip on Santarpio's. It's easily drivable from my house, and I've never tried it.
Finally, the article makes no mention of what we up here in Maine and NH call Greek-style pizza. Thicker, oily crust, more cheese than NY style. I suppose similar in many respects to 'deep dish' Chicago pizza. "Pizza by Alex" in my home town of Biddeford, Maine has made the best I've ever tasted of this style for decades, while also never changing their decor.
The nearest place that sells slices is a couple miles away. I'm outa here.
