Chick-fil-A (CHIK-fil-AY, a play on the US pronunciation of "fillet") is an American fast food restaurant chain headquartered in the Atlanta suburb of College Park, Georgia, specializing in chicken sandwiches. Founded in May 1946, it has more than 2,000 restaurants, mainly in the southeastern United States. The companys culture is influenced by its founder Truett Cathys Southern Baptist beliefs; all Chick-fil-A restaurants are closed for business on Sunday as well as Thanksgiving and Christmas. The chains origin can be traced to the Dwarf Grill (now the Dwarf House), a restaurant opened by S. Truett Cathy, the chains former Chairman and CEO, in 1946. The restaurant is located in Hapeville, Georgia, a suburb of Atlanta, and is near the location of the now-demolished Ford Motor Company Atlanta Assembly Plant, for many years a source of many of the restaurants patrons.
