Commonly known as "da Benito," this fish restaurant may look like all the other tourist-trap trattorias in the charming area near St. Peter's called Borgo Pio, but it's been a highly regarded staple among locals for years. Try their simple, classic seafood: heaping bowls of mussels and clams in a tomato broth, fettuccine with lobster, or their traditional fish fry, with shrimp, squid, and whatever else might be in season. Their refreshing dessert drink, a mixture of prosecco (dry sparkling white wine) and lemon sorbet, is perfect at any time of the year.
