That was some of the best service I've received in the airport. I've noticed that most waiters/waitresses tend to be short and not want to bother travelers, but my waitress was super friendly and asked about my flights and my day and I thought that was nice.
Onto the food. I ordered the magic mushroom burger, but got it with chicken instead of red meat. It was really good, especially with the sauce that's on it. I got it with sweet potato fries, which were okay. The two sauces that were served with them made up for the fries just being average. If I'm in the Charlotte airport again for a longer layover, I'd come back. Better than most of the options I passed that were mostly fast food or places that aren't necessarily substantial.
