I'm new to Philly, but I've tried a few pizzas, and this place has the best, so far. Service (at the smaller location, at least) is friendly and attentive, ingredients are all very fresh, and the prices are right. Recommend the Sicilian tomato pie, to which we added excellent toppings such as broccoli rabe and sliced mozarella. Antipasto plate is good, too.
Pros: Fresh ingredients, Great pizza, Good service
Cons: Not the best ambiance
