At the outset, I want to say that this four stars as airport restaurants go. I would not otherwise go here. It is, however, the best place to eat in CLT.
I've eaten two meals here in the past three days.
Lunch: an open-faced salmon sandwich, caprese salad, and iced tea. (No wine.) It was perfectly tasty. Service was prompt and friendly. The bill came to about $30--expensive generally speaking, but worth the money for a healthful airport meal.
Dinner: an open-faced chicken sandwich, a cheese plate, and iced tea. (Again, no wine.) The chicken sandwich was OK. The cheese plate had dried fruits, nuts, and a tasty selection of four cheeses (three soft, one hard), with quite large chunks of cheese. Mysteriously there were neither crackers nor bread, but instead a few triangles of pita. Spreading brie on pita was a strange experience, and not a particularly tasty one. (I suspect that the late night kitchen staff just isn't aware of how soft cheeses are generally served or consumed.) I quickly ran out of pita, and found myself just shoveling soft cheese into my mouth with my fingers. Again, service was prompt and friendly--especially for 10:15 at night--and the bill about $30.
I'm not in love with Beaudevin, but I hate every other food option at CLT--everything is greasy, reheated, meat-and-bread-laden fare, with hardly a fresh vegetable or fruit in sight. Sure, it's HMSHost-owned and -operated like every other restaurant in the airport, but even given that, Beaudevin is a breath of fresh air.
