I've only been back East a couple times, both to my best friend's place in Poughkeepsie. Knowing that I was a HUGE pizza nut, she arranged a Hudson Valley Pizza Tour for me... We had slices at five or six places. most NY style. Loved 'em all!
But the best one was actually a Detroit style pie, at a place called Hudson & Packard, right in the middle of Poughkeepsie.
Out here in NorCal, I don't think there are any really good NY style pizzas, but there some decent ones... For me, Chicago style is the best. Zachary's, a four-store chain in the East Bay is the bomb diggity! (Okay, I'm sure that's already an old phrase... and get off my lawn...)
There is supposedly a "California style", but I just call that fast-food pizza... like Chuck E. Cheese or Straw Hat. Still better than a hamburger in my book, but I can find better almost all the time.
I've been to Davenport, IA for their great traditional-jazz festival, and while there, had a couple other Chicago-style pies, one just over the river to Illinois, the other at Giordano's, a fairly large chain based in Chicago that makes a GREAT Chicago pie! Zachary's compares very closely to both of those places. BTW, if you've ever tried the chain "Old Chicago", that's a pretty good pie but not really Chicago style, no matter what they say.
The Davenport area also has its own style, Quad-cities style... do NOT try that! EEEEEEEEyuck!
If I ever actually make it to Connecticut, I'll refer myself to this thread.
