Come for the dance.
I've visited Lynn's a few times while in Charlotte on business. It's not the fanciest or classiest joint in town but the crowd makes up for it as they are certainly the friendliest and nicest. I have attended their Shag night on Thursdays and have had a great time. Always end up meeting nice people and making friends. It's the place to be in Charlotte on a Thursday night and I keep coming back. I highly recommend it.
