A hamburger or simply burger is a food consisting of fillings—usually a patty of ground meat, typically beef—placed inside a sliced bun or bread roll. Hamburgers are often served with cheese, lettuce, tomato, onion, pickles, bacon, or chilis; condiments such as ketchup, mustard, mayonnaise, relish, or a "special sauce", often a variation of Thousand Island dressing; and are frequently placed on sesame seed buns. A hamburger patty topped with cheese is called a cheeseburger.
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. Fast-food restaurants are typically part of a restaurant chain or franchise operation that provides 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.
Burger King Corporation is an American multinational chain of hamburger fast food restaurants. Headquartered in Miami-Dade County, Florida, the company was founded in 1953 as Insta-Burger King, a Jacksonville, Florida–based restaurant chain. After Insta-Burger King ran into financial difficulties, its two Miami-based franchisees David Edgerton (1927–2018) and James McLamore (1926–1996) purchased the company in 1959 and renamed it "Burger King". Over the next half-century, the company changed hands four times and its third set of owners, a partnership of TPG Capital, Bain Capital, and Goldman Sachs Capital Partners, took it public in 2002. In late 2010, 3G Capital of Brazil acquired a majority stake in the company, in a deal valued at US$3.26 billion. The new owners promptly initiated a restructuring of the company to reverse its fortunes. 3G, along with partner Berkshire Hathaway, eventually merged the company with the Canadian-based doughnut chain Tim Hortons, under the auspices of a new Canadian-based parent company named Restaurant Brands International.
