Chick-fil-A has long topped rankings of food quality and customer service. It is one of the most profitable chains in America, with average sales per restaurant reaching $4.4 million in 2016, according to a report from QSR magazine. For comparison, KFC sold $1.1 million per restaurant in the same period.
Teens' growing appreciation for the chain is most likely tied to the chain's aggressive growth in recent years. While Chick-fil-A has an established cult following in the South, the chain is now gaining fans in places such as New York City and the Midwest.
