Very small airport. No food service available, just some vending machines with chips, candy and sofa. Surprised that they didn't even have a small snack bar or small restaurant. I've been at much smaller airports with more available services. For an airport serving a Big 10 university, it's very much a small rural facility. Be sure to eat before heading to the airport.
On a the positive side, TSA was strange (like all small airports), but quicker than most small airports.
