It's the best way to order by the slice, soak in that classic pizzeria energy, and mingle with the crowd. We stood at the counter and tried the Mozzarella and the Fugazzeta. As a New Yorker who swears by thin crust, this thick, airy, Sicilian-style like pizza is a totally different beast, but I definitely understand the appeal. The Fugazzeta was a completely new experience for me. It's essentially a heavy base of dough and infused cheese buried under a massive layer of onions.
