Mud Flap Cafe at Exit 7 in Mandeville (Thoughts?)

I'm not a driver but I turn wrenches. Thinking of taking my family to this restaurant...been hearing about it alot on the radio. Anyone eaten here before?? Just wondering about the food. About an hour drive. Thanks. This is right East of Texarkana at Exit 7. Just into Arkansas. At J&J's truckstop.
