Though there has been some debate in the past about who makes the world's biggest burger, the Guinness Book of World's Records officiated at the weigh-in of a 29.5-pound burger at the Foxwoods Resort Casino's Fuddruckers restaurant. They granted the 18.5-in. wide by 8-in. tall burger the title of "world's largest commercially available burger." It costs $250 and must be ordered 48 hours in advance.
There is one burger that is said to be larger: the Mount Olympus burger at the Clinton Station Diner, in New Jersey. According to the diner, it weighs 50 pounds. A look at what goes into it reveals why it is not classified as the world's largest burger - Guinness officiation or not: it only has 25 pounds of beef in it. Twenty-five pounds of toppings on a bun, even with meat, makes a salad and not a burger. The Fuddruckers burger, by contrast, started with 33 pounds of beef and, while it did cook down to about 25 pounds, there were only 4.5 pounds of toppings on the final product, making it meatier than the Olympus and more title-worthy.
