The “Restaurant of the Knights” operates out of stone rooms off the Piazza die Cavalieri and a short stroll from the Campo that date to the 12th century, while the cooking is traditionally Tuscan but founded on the contemporary Slow Food principles of fresh and local. Being Pisa, this means seafood, including tagliolini with razor clams and a classic baccala, dried cod lightly battered and fried; some hearty meat choices, such as pappardelle with rabbit sauce and grilled steaks; and robust vegetable soups. You can get away with a one-dish meal here—in fact, it’s encouraged at lunchtime, when a crowd of local office workers packs in.
