Chick-fil-A

Chick-fil-A ranks #1 in the American Customer Satisfaction Index (ACSI) for fast food for the ninth consecutive year. With 3,000+ US locations generating $21 billion in annual sales, it achieves $8.7 million in average unit volume — nearly triple the industry average. Its chicken sandwich inspired a fast food culture war in 2019 and the chain's hospitality training is used as a business school case study.
