If you are at CLT and want food that isn't "fast food", I guess this would be it. In the strip of restaurants at the airport, Beaudevin is definitely more of a sit-down type and slightly upscale.
Went for breakfast....the breakfast menu is pretty small. I had the bagel with salmon lox, and it was pretty good. This place is going to cost you a bit more than most of the other food around, but it gives you a way to escape from the busy areas of the airport.
