Ah, you're in my old stomping grounds.
You're either gonna love or hate Colony. If you're from Boston or northern NJ, you're probably familiar with
bar/tavern style. If not, you may well think "wtf". For me, I grew up with Colony, and even though I don't consider it "best pizza", it's a unique taste/texture I miss like crazy being out here in Pgh. I try to always get there at least once when I'm back in CT. Ridgeway Pizza in Belltown and Riko's in Glenbrook are Colony knockoffs.
Other than that, Coalhouse and Remo's are both good for a more traditional Neopolitan. If you're up in the Springdale area, I'd also check out Amore's. I haven't been there since it reopened, but I used to go to the old Amore's which was very good. Bruno diFabio started there a long time ago and since became a TV pizza star and reopened the place 2-3 years ago. I've heard good things.
You can also find Greek pizza, which another uniquely New England thing at Hope Pizza in Glenbrook. Try it, make up your own mind. It's very popular and about once a decade I get a jones for it.
And while the content on the
Stamford Pizza Tour is about 10 years old, it's probably worth your while to take a look.
