Fast food is a type of mass-produced food that is prepared and served very quickly. The food is typically less nutritionally valuable compared to other foods and dishes. While any meal with low preparation time can be considered fast food, typically the term refers to food sold in a restaurant or store with preheated or precooked ingredients, and served to the customer in a packaged form for take-out/take-away.Fast food restaurants are traditionally distinguished by their ability to serve food via a drive-through. Outlets may be stands or kiosks, which may provide no shelter or seating,or fast food restaurants (also known as quick service restaurants). Franchise operations that are part of restaurant chains have standardized foodstuffs shipped to each restaurant from central locations.
