Charlotte is the famous home of layovers for most US Airways flights, and this lovely wine bar makes unexpected delays a pleasant surprise. Not even being sarcastic here.
A co-worker and I used a small 1.5hr layover in Charlotte to swing by (it's between major terminals) to grab a quick bite to eat. The interactive iPad set up tells you a lot about the wine options available. The waitress was also spectacular at recommended local North Carolinian white wines to taste. She was also more than willing to give samples, which was nice.
In the way of food, we grabbed the cheese plate. The apple compote, cheese, dried fruit, and bread was a great add on and filled two of us up for lunch. (Not the most filling, but it was enough to tide us over for four more hours.)
Nice bonus: there was a grand piano outside the restaurant, which someone played. Not sure if he was hired or just another traveler on a layover, but it was fabulous!
