(This post is based on a visit to the mini-chain's Spring St. location, which is closed.) You can't tell this slice is actually a snip, can you?
Not that it affects the flavor, but the tradition in Rome, and the practice at this "pizzeria Romana" branch of Numero 28, is to apportion individual servings with scissors. Reportedly the proprietors make a white pie like this one, but with walnuts. This version ($4) loses the nuts and keeps the tomato sauce, as well as mozzarella; gorgonzola and (to a gentler degree) pear are the most prominent notes. They infiltrate the oil on top, too; don't drain it off!
