re: "not copying" Layne's, do yall mean that both places came up with the idea on their own? it can't be their founding dates. Layne's open in 1994, Cane's opened in 1996.
When I was doing relief work in Oct 05 down in N.O., Rasing Canes in Metarie was one of the very first restaurants to re-open. People would line up there for hours just to eat some chicken strips (and only the drive-thru was open). They have one in Lewisville now. I ate there and was not too impressed with it. I definitely would not wait in line a couple of hours to eat their food.
