Chick-fil-A is one of the largest American fast food restaurant chains and the largest specializing in chicken sandwiches. The company is headquartered in College Park, Georgia. Chick-fil-A operates 2,875 restaurants, primarily in the United States. The chain has locations in 49 states, the District of Columbia, and Puerto Rico. The company also has operations in Canada, and previously had restaurants in the United Kingdom and South Africa. The restaurant serves breakfast before transitioning to its lunch and dinner menu. Chick-fil-A also offers customers catered selections from its menu for special events.
Many of the company's values are influenced by the Christian religious beliefs of its late founder, S. Truett Cathy (1921–2014), a devout Southern Baptist. Reflecting a commitment to Sunday Sabbatarianism, all Chick-fil-A restaurants are closed for business on Sundays, as well as on Thanksgiving and Christmas Day; to honor the Western Christian liturgical season of Lent, Chick-fil-A promotes fish sandwiches in respect of abstinence from meat that characterizes that part of the Church Year. The company's conservative opposition to same-sex marriage has been the subject of public controversy, though the company has begun to loosen its stance on this issue.
