Luigi Pomata cooks Carloforte tuna in Cagliari, three rooms and a port-facing terrace above Viale Regina Margherita, raw fish to open and red tuna to follow.
Order: Red tuna, raw then seared, the house speciality.
Tip: Lunch service runs 13:00 to 15:00 Tuesday to Saturday and is the cheaper way in; tinned house tuna is sold to take home.

Terra sits on the ground floor of Palazzo Tirso in Cagliari, a central design kitchen turning Sardinian seasonal produce into a gourmet carte.
Order: The seasonal Sardinian tasting menu.
Tip: The same hotel runs the Cielo terrace upstairs, so book Terra for dinner and move up for a drink over the Golfo degli Angeli.

Antica Hostaria on Via Cavour is the old-school Cagliari osteria of the Marina, dark wood and a fish-led list of Sardinian classics under Antonio Mura.
Order: Fregula con arselle, or the baked capon with artichokes and potatoes.
Tip: Closed Sunday. The room started as a mid-nineteenth-century inn and the kitchen still leans on the fish list rather than the printed classics.

Trattoria Lillicu has fed the Marina from Via Sardegna for generations, marble tables, no printed menu, and whatever the Cagliari boats landed that morning.
Order: Spaghetti with arselle clams and bottarga.
Tip: Do not ask for a menu, the waiter recites the catch; arrive by 13:00 or after 14:00 to miss the queue. Monday the trattoria stays shut.

Su Cumbidu on Via Napoli feeds the Marina fixed-price Sardinian menus under brick arches, culurgiones and seadas at prices Cagliari students accept.
Order: Culurgiones, potato and mint, in tomato sauce.
Tip: The set menus are the value play at around €20 to 30; go early, because groups book out the arched back room.

Stella Marina di Montecristo works the far end of Via Sardegna in Cagliari, sixty covers of maritime kit and fish bought fresh that morning.
Order: Whatever came off the boats that morning, cooked simply.
Tip: It shuts for a variable stretch in August, and the sixty covers go fast in summer, so call the mobile number to hold a table.

Sa Schironada on Via Baylle runs long hours for the Marina in Cagliari, Sardinian fish and roast plates and a crisp fritto misto from the Gulf.
Order: Zuppa di cozze with pane carasau, then seadas.
Tip: Open every day and late, which makes it the fallback when the smaller trattorias in the Marina have shut their kitchens.

Trattoria da Serafino works a corner of Via Lepanto in Cagliari, an air-conditioned room of local fish plates and a back room for long lunches.
Order: Whatever local fish is on the board that day.
Tip: Closed Wednesday; the private back room takes the business lunches, so the front fills with regulars.

Osteria Kobuta cooks Japanese-Sardinian plates in Cagliari off Largo Carlo Felice, a seasonal menu built for sharing in a room of maybe ten tables.
Order: The seasonal sharing menu, start to finish.
Tip: Closed Tuesday, and the kitchen writes a new menu each season; WhatsApp booking is the fastest way to get a table.

Panefratteria builds its Cagliari menu on pane carasau, the sheet bread softened into pane frattau and zuppa gallurese in a modern room on Via Azuni.
Order: Pane frattau, tomato, pecorino and a poached egg.
Tip: Closed Tuesday; there is a garden at the back and the grappa and Sardinian wine list is longer than the food menu.
