On a Carnival Cruise in 2026, you can essentially eat as much as you want, as the majority of dining options are included in your base fare. The Lido Marketplace buffet, Guy’s Burger Joint, BlueIguana Cantina, and the Main Dining Room offer "all-you-can-eat" experiences where you can order multiple appetizers, entrees, and desserts during a single sitting. There are no limits on the number of times you can return to the buffet or visit the 24-hour soft-serve ice cream and pizza stations. While most food is complimentary, Carnival does charge extra for "Specialty Dining" venues like the Fahrenheit 555 Steakhouse, Bonsai Sushi, and Rudi’s Seagrill, which typically require a per-person cover charge or a-la-carte pricing. Additionally, items like specialty coffees, soda, and alcoholic beverages are not included unless you have a specific beverage package. Overall, the "unlimited" nature of the food remains a core part of the Carnival "Fun Ship" experience, encouraging guests to try a variety of dishes without worrying about an individual bill.
