I'm traveling a lot lately and I always have a layover in Charlotte. But when I don't have a layover, I always try to find a similar experience as Beaudevin. This might be, the best airport restaurant in America.
I mostly go in and eat something light like their flatbreads. They are always cripsy and full of flavor, no matter which one you order. The wine selection is great and not expensive considering you are in an airport.
The staff will always recognize people that come through a lot.
Pro tip: They have outlets at the bar but they are hidden against the top.
