Carnival's Warm Chocolate Melting Cake dish is served in the main dining room for dinner. This dish is typically available on the menu each night of the cruise in the main dining room. If prepared correctly, the upper part of the dish is solid chocolate cake and directly below is a large melted warm chocolate.
Warning: This food item can be addicting as well as very filling.
There are some Carnival ships that serve Spinach & Artichoke Dip in the main dining room as a dinner appetizer on one night of the cruise. If your ship offers this item, I recommend trying it. The chips are regular tortilla chips. The dip is very tasty and filling.
If your Carnival ship has The Taste Bar, you need to visit it on the night of the cruise when you can sample Cucina Del Capitano. On this night, the sample plate will include a meatball and bruschetta. While both are tasty, the meatball is delicious. It is usually covered with cheese and marinated in a red sauce.
Typically, on the second day of the cruise, Carnival will serve Key Lime Pie in the buffet. In my opinion, this is the best dessert served in the buffet out of any days of the cruise.
On some Carnival ships, in the main dining room, you may see a main course named "Shrimp & Fries". This is always something I get when I see it offered. Typically, this dish comes with shrimp, french fries, a slice of watermelon, and a bowl of ketchup. While this is a greasy meal, it is extremely tasty!
All Carnival ships have a deli in or near the buffet. While the deli offers a variety of sandwiches, one of the many popular options is the Pastrami on Rye sandwich. This sandwich contains pastrami meat, mustard, cheese (depending on the crew member making it), and rye bread. The sandwich is usually grilled and served warm.
The Turkey Wraps sandwiches served by Carnival's deli are also delicious. The way the turkey wrap sandwiches are created can vary by crew member, but the sandwich typically contains turkey, lettuce, tomato, and a tortilla. This sandwich is on the deli menu's cold item section.
Carnival ships typically serve cookies in the buffet during the lunch buffet hours. There are two types of cookies available. The cookies served can vary in texture and moistness, but I have found the cookies taste the same on all ships.
