Corona Blu (Deck 10): Costa Diadema's buffet restaurant, designed to be casual and comfortable, is an explosion of colors and flavors. During the day, you'll find tables both inside and outdoors around the pools. Enjoy breakfast (7:00 a.m. to 11 a.m.), lunch (noon to 3:00 p.m.) and tea or snacks (4 p.m. to 5 p.m.) here at your leisure. Once tea is over, there is no more buffet service until breakfast the following morning. In the evening, Corona Blu is transformed into an informal, open-seating dinner restaurant. Passengers who choose this option are assigned to Corona Blu as their primary free dinner restaurant throughout the cruise. The benefit of dining here at night (6:30 p.m. to 10:30 p.m.) is just showing up when you wish rather than at a set time; the menu here is the same as in the two main dining rooms. On the flip side, there's no buffet option on the ship for a casual dinner.
During buffet hours, coffee and tea are available free of charge only at breakfast and hot tea at tea time. Water (for free and not the bottled variety) can be had from dispensers at breakfast and lunch. Food stations are clearly marked. Breakfast is Italian-style cold cuts, cheeses, an amazing array of breads and pastries, fruit, cereal and yogurt. Nothing cooked. A
nice touch is the coffee pot set on each table. Lunch has more variety, though dishes don't change much from day to day throughout the cruise. Stations include high-quality cold cuts, cheeses, breads, hot dishes (stews, vegetables, fish), three Asian dishes (chicken stir-fry, fried rice), grilled meats, salads, paninis, focaccia and desserts. There are no trays to carry, and your cutlery is already on the table in a cutlery stand. Tea time brings cakes, cookies, small sandwiches, fruit and tea.
The buffet is always crowded, but if you move to the back of the ship, further from the food stations, you're apt to find a quiet seat near the window.
A hamburger grill by the midship pool is open during lunch hours. At the aft Lido Stella del Sud pool, burgers are sometimes served later, around 1:00 p.m. to 4:00 p.m.
Note: During the day, Corona Blu is referred to as Trattoria Lido Diana. It's all the same place.
