I know where the Big Chicken is ! I use to go there when they had curb service . It came in real handy when I was breast feeding too .I could go out and eat in comfort .That was over 40 years ago though .
It is a totally new building now. The original was torn up in a tornado and KFC rebuilt it after a big marketing blitz wherein they invited people to vote on the new design. Of course we all picked the original design but KFC included more floorspace and made it stronger to withstand the elements in the future.
