The food system, including food service and food retailing supplied $1.24 trillion worth of food in 2010 in the US, $594 billion of which was supplied by food service facilities, defined by the USDA as any place which prepares food for immediate consumption on site, including locations that are not primarily engaged in dispensing meals such as recreational facilities and retail stores. Full-service and Fast-food restaurants account for 77% of all foodservice sales, with full-service restaurants accounting for just slightly more than fast food in 2010. The shifts in the market shares between fast food and full-service restaurants to market demand changes the offerings of both foods and services of both types of restaurants.
