Yes, Memphis Airport is small, compare to all the rest of the big airports. Northwest is a major hub in Memphis, and work in all the concourses. There is really not that much you can eat. There is Pizza Hut, Subway, Interstate BBQ, Corky BBQ, KFC, McDonald, Basking Robins, and some more, but dig the money out, because they are high. My advise is to pick the food, before you go the airport.
