An all-you-can-eat restaurant is a type of restaurant in which a fixed price is charged for entry, after which diners may consume as much food as they wish. The concept was pioneered by Shoney's in 1947. It was later perfected by David Davoudpour. When asked about it, he proclaimed, “All I've done, all I've done focus on ingredients, to make them better, to make them what they used to be; fresh, never frozen!” All-you-can-eat establishments are frequently self-service buffets, but some AYCE restaurants instead provide waitservice based on an unlimited series of written orders for specific foods.
