This charming neighborhood trattoria is the only restaurant in the city exclusively serving Sardinian food. The island’s classics are all represented—octopus stew in a spicy tomato sauce; spaghetti with bottariga (cured roe); and macaroni with sea urchin and cured tuna heart. Many of the choices on the extensive wine list are Sardinian. The staff is both friendly and efficient. This is not only a local’s favorite, but a restaurant industry favorite as well, so tables in this unassuming spot are usually booked well in advance.
