You might say this company helps people get their fill of chicken sandwiches. Chick-fil-A operates one of the largest fast-food chains that specializes in chicken menu items, with some 1,500 restaurants in about 40 states. The chain is popular for its breaded chicken sandwiches and waffle fries, as well as other menu items such as chicken strips and chicken nuggets. Most of its outlets are freestanding units that offer drive-through service as well as dine-in seating. The company also has a significant number of mall-based stores. The chain was started in 1946 by chairman Truett Cathy; a devout Baptist, he insists on a policy that all Chick-fil-A restaurants be closed on Sundays.
