Sicily's pizza in Flint MI is the jump off!
That's about the best Dallas has. I don't think Dallas, or Texas for that matter, has any pizza that can rival Chicago and the Northeast.
In order of pretentiousness, from the Raleigh-Durham area:
1. Lilly's Pizza - Local/Organic/Hipster. I rarely leave without shaking my head, but the pie is awesome. Dante's Inferno is highly recommended. They just opened a store closer to me (which makes their second).
If other CT'ers are in Groton try out Ciro's on Long Hill Road....Good stuff!!!
How could it possibly be better than Chick's Pit Garbage Truck Special?
Being a New Yorker living in Chicago has not been easy...I have constant battles with my Chicagoan Inlaws. I do not like deep dish(nor do they), but even the thin crust to me is...meh. Its funny that its cut in squares(at most places) like your in 3rd grade. I will say that PIECE Chicago is excellent(however the owners are from New Haven)
I have also been to Pepe's in New Haven and think its top notch pizza
But my favorites in NY
Grimaldi's
lombardi's
Spumoni Garden(L&B's) in Brooklyn
Difaros Brooklyn
Johns
Wick's in Louisville, KY. It's hands-down the best pizza I've ever eaten. It's a thick crust with amazing sauce and only the best toppings, and comes in absolutely massive sizes to feed a huge group. It's not greasy either, as a lot of places are.
