If you're stuck in CLT during a layover (As I was for three hours on my way to LAS) this is a nice, quiet, comfortable place to enjoy some small portion tapas and a glass of wine/cocktail/cup of coffee away from the herds rushing to and from their CRJs.
I had the ceviche and roasted artichoke salad.
The Good; Service was excellent. The waitress was attentive and made every effort to come back and check in to see if I have everything I wanted. The menu is head and shoulders more interesting and better for you than the options out in the food court. The layout and design of the seating offers you everything from a nice leather couch to the bar to standard tables with lovely cushioned chairs. Head and shoulders above any other establishment in this airport.
The Bad: While the menu is really interesting and has lots of tasty sounding options, the ingredients they are using are not the best. The Ceviches guacamole was dark and slimy and settled entirely to the bottom of the dish. The chicken I added was rubbery and pre-cooked, not nearly as nice as the salad itself. Also, hot tea may not be the most ordered item in a wine bar but considering the 'higher end' nature of this place having more than mint, english breakfast and earl grey doesn't take much effort.
Overall with a couple small additions this place wouldn't just be the nicest in the airport, it would be a standout anywhere.
