I like their lemonade. It's pretty sweet though, not really for everyone. If there was one complaint I have about CFA, it's that their chicken isn't as crispy as I'd like. Also, I like the buns they use for the club. I request the multigrain bun to go with the spicy deluxe. Better than the plain buns imo.
Our go to sauce is their CFA sauce. I dip my waffle fries in that, better than ketchup. CFA locations here are always clean, they are always polite and rarely get an order wrong, and when they do get it wrong, they'll often comp you a free sandwich for the next trip.
I know they get a lot of grief because of the religious roots and being closed on Sundays, but they're are well run franchise. That and they're pretty consistent from location to location. I haven't really been to a bad location yet.
