Chick fil a basically invented the deboned chicken breast. What you are getting is a hunk of southern fried, white meat chicken breast, no bone, on a bun with pickles (the original sandwich). It is not ground up mystery stuff...it is a hunk of juicy fried chicken without the bone. and southerners love their fried chicken. The lemonade is awesome, too. That's it, in a nutshell. Simplicity at its finest. As the years have gone by, they have also come up with some amazing shakes. The peach shake that they only serve in summer will knock your socks off.
When I was a kid, my mom ( who was from the northwest and was transplanted against her will in the south), used to drive us out to Crabtree Valley Mall under the guise of going shopping. She rarely bought anything, and I always suspected it was a cover to get her Chick fil-A fix. It was a treat for us. And you would have never caught my mom in a McDonald's.
