Denver International Airport is home to a number of different fast food restaurants, but Chick-Fil-A is the only one that is open 24 hours a day. This is a popular choice for travelers, as it is always open and convenient.
Chick-Fil-A has a number of locations throughout the airport, so there is likely one close to where you are. If you are looking for a fast food option that is open late into the night, Chick-Fil-A is the perfect choice.
