You pay a premium here for the view, and it's admittedly a killer one. City Lights is beautiful - an expansive, spacious rooftop with panoramic views of the Charlotte skyline. I was there a few weeks ago and they had a keyboardist covering Billy Joel tunes (quite well, too) so that didn't hurt either. You'll feel like a B-list celebrity for hanging out here.
Go on Sundays - take advantage of the rose-all-day promotion, even if, like me, you're not crazy about sweet pink wine. It's a damn good price for alcohol on a pretty rooftop. Just go here so that you can say that you did.
