For fritti: Start every pizza meal in Napoli with fried things like frittatine (basically béchamel-bound pasta croquettes) and crocche’ di patate. I love these things at Attilio and 50 Kalò and I Decumani (Via dei Tribunali 58-61) does good fritti, as well. But basically every place along Via dei Tribunali does fritti and pizza a portafoglio from roadside stalls for a quick bite on your feet.
