              On your cruise, every breakfast, every lunch, every dinner and every snack will have its own special ingredient: the flavour of Italy that is all around you on a Costa holiday. All the restaurants serve specialities made with top-quality ingredients and prepared with the love of food for which Italians are famous.

              Each morning there is a buffet breakfast with traditional Italian items, including a wide range of breads, croissants, sweets and cakes – all homemade – as well as cold cuts, cheese, fruit, yoghurt and cereals. Every day, for both lunch and dinner, a region of Italy will be the special guest at your table, with menus inspired by traditional local cuisine: you can try the famous fillet of beef Rossini on the day dedicated to the Marche region, cappelletti pasta with braised beef from Emilia Romagna, or exquisite Sardinian fregola pasta with fresh vegetables. And for anyone who wants to enjoy the most sophisticated Italian delicacies, the menu offers a selection for a small extra charge: delicious Grana Padano cheese and Parma ham, the genuine Milanese 300 g veal cutlet and the freshest shellfish.
