It doesn’t hurt that their food, especially the chicken sandwiches are pretty good.
I’m pretty sure that they also get a lot of traffic because of their children’s play area inside the restaurants, meant for kids 4 and under, but where kids up to 9 can be seen playing. When we ask our grandchildren where they would like to eat, most times they mention Chik-fil-A, because they want to run and play inside.
Yeah, that's gotta be it. Couldn't be the delicious food, the wonderfully pleasant and courteous staff, and outwardly expressed Christian values. LOL
