Gino Sorbillo
There are a few restaurants called Sorbillo along Via dei Tribunali, but this one is world-renowned. Order the same thing the locals do, namely a basic Neapolitan pizza (try the unique pizza al pesto or the stunningly simple marinara, with just San Marzano tomatoes, wild garlic, and oregano) that's cooked to perfection by the third generation of pie makers who run the place. The pizzas are enormous, flopping over the edge of the plate onto the white marble tabletops. Be warned though, there is no booking system, and you'll have to line up for a while, but an entrepreneurial local on a nearby balcony often entertains the crowds with Neapolitan songs.
