On a little beach where pirates used to build and launch boats, this laid-back trattoria has long been a favorite Positano landmark. The pirates are long gone, but their descendants now operate the free ferry to and from Positano (every half-hour in the morning)—look for the boat with the red fish on the mast named for the restaurant—or make the steep descent from the main coastal road at Laurito. Sit under a straw canopy on the wooden terrace to enjoy totani con patate (squid and potatoes with garlic and oil); then sip white wine with peaches until sundown. Some diners even swim over, so bathing suits are fine. Da Adolfo gets busy, so ask your hotel to book a table for you: personal reservations are often not honored.
