With more than double the sales of its nearest competitor in the chicken market, KFC, Chick-fil-A is far and away the biggest chicken chain in the United States and the third-largest restaurant brand overall. Chick-fil-A is known for its food and for the religious convictions of its founder, S. Truett Cathy, a devout Southern Baptist; the store is closed on Sundays. The chain is run by his son, Dan T. Cathy, who is president, CEO, and chairman; the family has courted controversy for its donations to anti-LGBTQ+ organizations.
