Fast-food restaurant

A fast food restaurant, also known as a quick service restaurant (QSR) within the industry, is a specific type of restaurant that serves fast food cuisine and has minimal table service. The food served in fast food restaurants is typically part of a "meat-sweet diet", offered from a limited menu, cooked in bulk in advance and kept hot, finished and packaged to order, and usually available for take away, though seating may be provided at the restaurant. Fast food restaurants are typically part of a restaurant chain or franchise operation that provisions standardized ingredients and/or partially prepared foods and supplies to each restaurant through controlled supply channels. The term "fast food" was recognized in a dictionary by Merriam–Webster in 1951.

Arguably, the first fast food restaurants originated in the United States with A&W in 1919 and White Castle in 1921. Today, American-founded fast food chains such as McDonald's (est. 1940) and KFC (est. 1952) are multinational corporations with outlets across the globe.

Variations on the fast food restaurant concept include fast casual restaurants and catering trucks. Fast casual restaurants have higher sit-in ratios, and customers can sit and have their orders brought to them. Catering trucks often park just outside worksites and are popular with factory workers.

Some trace the modern history of fast food in America to 7 July 1912, with the opening of a fast food restaurant called the Automat in New York. The Automat was a cafeteria with its pre-prepared foods behind small glass windows and coin-operated slots. Joseph Horn and Frank Hardart had already opened the first Horn & Hardart Automat in Philadelphia in 1902, but their "Automat" at Broadway and 13th Street, in New York City, created a sensation. Numerous Automat restaurants were built around the country to deal with the demand. Automats remained extremely popular throughout the 1920s and 1930s. The company also popularized the notion of "take-out" food, with their slogan "Less work for Mother".
