The place to go for Rome's extraordinary carciofi alla giudia (fried whole artichokes), Piperno has been in business since 1860. The location, up a tiny hill in a piazza tucked away behind the palazzi of the Jewish Ghetto, lends the restaurant a rarefied air. Try the exquisite prosciutto and buffalo mozzarella plate, the fiori di zucca ripieni e fritti (fried stuffed zucchini flowers), and filetti di baccalà (fillet of cod) to start. The display of fresh local fish is enticing enough to lure diners to try offerings from sea instead of land. Service is in the old school style of dignified formality. This is a very popular destination for Sunday lunch.
