Restaurant model based on a single price for any amount of food
An all-you-can-eat restaurant (AYCE) 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. 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.
Buffets
The all-you-can-eat buffet has been ascribed to Herb McDonald, a Las Vegas publicity and entertainment manager who introduced the idea in 1946.[1][2]
A 2011 study showed that the amount of food consumed increases with the price charged for the buffet.[3]
