This is a restaurant managed by HMS Host, so, expect the "normal" bad service/quality compared to street restaurants.
Regardless, this place is probably one of the best ones around the CLT Airport. It is a greasy spoon for sure but fits the bill if you are looking for a quick meal that is not "junk".
I have only had breakfast here but both of the dishes I have ordered: eggs with bacon and the parfait were good. The yogurt wasn't that awesome but wasn't expecting that much anyway.
