Thanksgiving weekend, Las Vegas: A camera journeys through Sin City's all-you-can-eat buffets and finds a kaleidoscope of characters behind the food—from tireless chefs preparing gargantuan bowls of ambrosia, to servers who bus endless plates, to hungry diners in search of a culinary jackpot and a portion of the American dream. "The buffet is the happiest and saddest place," says Pierre, a meat carver at the New Frontier's buffet. This documentary brings the happiness and the sadness of the buffet to light, taking the audience on a wild gastronomic voyage behind the scenes of an all-American binge ritual. Buffet follows the food: from kitchen to cornucopia, table to mouth, waste bin to local farm where 6,000 eager pigs feast on buffet leftovers. All along the consumption chain, a diverse cast of characters share their desires, their weaknesses, their pleasures, and their shames. The camera rolls as the savory promise that greets diners turns to gluttony, then despondence—and sometimes, a flickering hope for something more than just "all you can eat."
