Umberto
Run by the Di Porzio family since 1916, Umberto is one of the city's classic restaurants, combining the poshness of its neighborhood, Chiaia, and the friendliness found in other parts of Naples. Try the paccheri d'o treddeta ("three-finger" pasta with octopus, tomato, olives, and capers), which bears the nickname of the original Umberto, who happened to be short a few digits. Owner Massimo and sisters Lorella and Roberta (Umberto's grandchildren) are all wine experts and oversee a fantastic cellar. Note that Umberto has been catering to diners with a gluten allergy, as well as to vegetarians, for years.
