#2 Fast Food Restaurant

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 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, offering a hybrid between counter-service typical at fast food restaurants and a traditional table service restaurant. Catering trucks (also called food trucks) often park just outside worksites and are popular with factory workers.
