In the frenzy over blistered Neapolitan pizzas made with tomatoes blessed by a Catholic priest and quadruple zero flour, the appreciation for a plain ole cheese slice is in threat of extinction. Not to mention, when the urge strikes for a slice of hot, greasy goodness, waiting for a table at Delfina Pizzeria just won't cut it. A slice has to be fast, cheap, and in our control. (And preferably near a good dive bar.)

So who's got the best? After tasting my way through the city, I picked Tony’s Napoletana. It satisfies all cheese pizza requirements: Oozy mozzarella, tangy tomato sauce, a flavorful, chewy crust and a forbidden—yet delicious—trickle of grease.Very close runner-up: Arinell’s. Classic fold-and-go slices that hit the spot every time. Plus, pizza just tastes better with punk rock.
