Attanasio
For a hot-out-of-the-oven sfogliatella, Naples's tasty ricotta-filled pastry, try the justifiably famous Attanasio (you can grab one as soon as you get off the train). Note, though, that this place is slightly hidden away off Piazza Garibaldi and shouldn't be confused with the touristy restaurant of the same name on the piazza itself.
