On South Main Street in the heart of Providence, R.I., Al Forno offers a quintessential Italian dining experience for those who can’t afford the flight. Husband-and-wife owner-chefs George Germon and Johanne Killeen received the Insegna del Ristorante Italiano from the Italian government, a rare honor for Americans, attributable to their informed passion for pasta along with their invention of the grilled pizza. The restaurant bakes their pies in wood-burning ovens as well as on grills over hardwood charcoal fire. Their most notable grilled pizza? The margarita. It’s served with fresh herbs, pomodoro, two cheeses, and extra-virgin olive oil.
