Mcghee Tyson Knoxville TN restaurants?

[GCM]

Does anyone know what if any restaurants are inside Mcghee Tyson other than Ruby Tuesdays? I have not been able to find anything other than Ruby Tuesdays. My family will need to eat lunch before boarding. Flight is 12:45 and we won't be hungry before we arrive. We would like just a quick lunch, nothing major, to hold us over until we arrive at MCO.

Thanks!
