If its really convenient for the drivers ie: not a long walk, because time is always a big consideration even when getting chow AND the food is something to be yakked about. I think it sounds like a winner location. Along with the food a really good cup of coffee, large and cheap with thermos fills available would be a plus. keep the food driver friendly, something that can be eaten while driving but made fresh like fresh not frozen burgers or homemade meatloaf sandwiches. You dont mention sit down dining that can also be a plus.
