On a Carnival Cruise, the amount of food you can eat is virtually unlimited for most included dining venues. In the Main Dining Room, you can order multiple appetizers, main courses, and desserts if you wish, and the Lido Marketplace buffet offers endless helpings throughout the day. While some specialty items like lobster or steak in the main hall may carry a small surcharge for a second portion, the vast majority of food—from Guy's Burger Joint to 24-hour pizza—is "all-you-can-eat." The only real limit is your physical appetite and the operating hours of specific venues.
