Aside from the obviously delicious chicken sandwiches and waffle fries I love to come to Chick-fil-a because they are just so dang polite. I say "thank you" as many times as I can just to hear them say "my pleasure"!
My kids love their shakes more than any other ice cream treat anywhere!
I also love that they are closed on Sundays (except when I want waffle fries on Sundays!) and their conservative stance and support for First Responders. I am a customer for life.
