This is a lovely restaurant. My wife and I love to stop there, the sushi is passable and the panini sandwiches are delicious. The wait staff is typically good but occasionally there is the bad apple in the bunch. If you go during the day they can be a bit pushy about getting you out so don't try and set up shop. The evening staff is fairly gracious and can usually recommend good wine. Over all I score a 3 because the day staff has been a bit rude, I prefer wait staff to ask if I want another drink rather than just handing me a bill which basically says to me, "get out."
In short, the food is good (not ground breaking), most of tthe staff is knowledgeable and the atmosphere is nice. Lacks character like most Charlotte places but is one of the few descent wine bars in the uptown area.
