I know we've argued about it multiple times in the forums. Arenafoot and jmjustin6 always mention these two (although I can't remember who likes which).
Anyways, I just tried Cane's, and it was awesome. I'll try Zaxby's within the next few days. Yes, while my wife is off working, I am sampling the fast-food joints they have down south that we don't have at home. Don't worry, fancy restaurants are being visited with her in the evenings.
Also tried "Steak N Shake" and was immensely impressed. Such a great deal. There is no way you can find a table service restaurant back home at these prices. WOW! Southern living is alright!!
