I love Regina's in the N.E. when it's hot and fresh, but I haven't been able to find a decent place in my area (Sharon, Norwood, Stoughton, Walpole, Foxboro, etc.). I'm willing to travel a bit to get it. I'm looking for a shop that serves up REAL pizza; fresh mozzarella, maybe button mushrooms. I'm looking for a place that would appeal to a "pizza snob". Other examples of what I like are Luna and Harry's (WH Center) in CT, Lombardi's in SOHO and (used to be) in Philly. Pepe's in New Haven is ok, but I think the latter are better. Just so you have an idea what I'm looking for.
While you're at it, maybe a few reco's in Providence for when I'm down there on occasion ...
