flatbread pizza, 'nuff said. a lot like bertucci's since pizzas are cooked in wooden grill, only better.

papa gino's are pretty good, too.
as for mom and pop's joints, Tasty's in peabody, mass makes pizzas that are out of this world. the amount of cheese, tomato sauce, grease and dough all are in perfect proportions.
