Location, Location, Location. Food and drinks are pricey for what they are, I'm not one to complain about the price of food or drinks, but they were nothing I'd brag about. The view is what did it for me, seeing all of Charlotte while dining is a nice treat. The elevator is a bit confusing if it's your first time, but it's an issue that's easily overcome. The service wasn't too impressive, but overall not horrible.
I wouldn't go there on the regular, but it's fun to bring people new to Charlotte or just visiting.
