When I feel like treating myself to a pie the way it should be, there's no questions the place to go is Zagi's.
Thin crust, the perfect heft and the Guiness carmelized onions are divine. The slices they have ready to eat are usually spot on and offer a selection other than the usual cheese and pepperoni. My favorite combination is the Prosciutto, Mushrooms and Guiness Carmelized Onions. That's a tasty pie!
