Why cruise on this ship?
Costa Diadema, launched in 2014, is the latest addition to our fleet. It is built for relaxation and fun with lots of on-board activities, scintillating bars, gourmet restaurants and the spa area.
Dining
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.

Samsara Restaurant
Samsara's cuisine is the epitome of the philosophy of wellbeing. In this Japanese-style restaurant, you can expect charm, elegance and discretion, both at the table and from the service.

Entertaining
There are a thousand facets of fun on board. With Costa, the Italian attitude of a “spectacle becoming art” is all around you. With shows and activities that are always different; you will simply have to choose. Musicians, acrobats, magicians, mime artists and bands are ready to help you discover that shows come in many forms and shapes and all will appear on stage, on board, to enable you to experience some unforgettable moments. At the theatre, for example, where the artists make you laugh, dream, stir your emotions, entertain children, and in the most important moments of the cruise when singers, DJs and dancers perform in the numerous bars and lounges on board. And you too can be a star when you take part in our talent contest: The Voice.
