Yeah,Chick-fil-A is ridiculously popular here,the one nearest me has two drive thru lanes and they are usually packed from lunchtime on.I had it yesterday for lunch. Chicken bacon Swiss for me. It's next to a Chick-fil-A, but their lines are normally way to long for impatient people, so Arby's it was. Can't complain though, their service is normally spot on.
I might have to give something else a try at Arby's but I love their Ruebens!
