A brief history of my old Pizza haunts, feel free to post in with your opinions. Something in the back of my head is screaming, Are you nuts? Don't tell them.
Working and playing in Boston for many years, we used to go to the Rat, catch a band and afterwards go to Nemos Pizza. Given we were drinking, I thought it came close to New York pizza. I think both are gone now. I was at Ninos the other day on Charles. His pie is pretty good.
I agree with Scott that Regina's in the North End is probably the best Pizza in Boston and maybe New England. Although, way back when there were two pizzerias in N. Conway; Elvios and Marcellos. I haven't been to them in awhile. Bertuccis used to be good, the original store in Somerville with the Bacci ball court downstairs, those were the days. Santarpios in East Boston is difficult and the pizza is often burned. It is good but not consistently good.
Here are some to try:
Maria di Napoli in Nonantum
Stella's in Watertown
I am not a fan of Hellenic pizza, it is too greasy and after a slice you get that heavy, unpleasant feeling in your stomach.
Sheet pizza made fresh in an Italian bakery can be surprisingly good.
Iggy's bakery has an interesting choice of sourdough sheet pizza with unusual yet acceptable toppings. I am still laughing about one of the members using "Pineapple on pizza, that's a cake". I feel the same way, what a great signature and what a great site.
