It's hard to go wrong at a pizza place in Boston, but this place is a notch above the rest. Doesn't matter much what you get, it's going to be thin and it's going to be good. I tend to stick to pepperoni and cheese but that's more of a personality flaw than a recommendation.
The staff is consistently short, brusk, and downright rude. Welcome to Boston. Get used to it. Or move back to California.
