I found Chatpowa to be quite a stylish site, though it does seem to promote it's other services quite heavily. Chatpowa is strictly 18+ and you'll have to enter a handle upon entering the site, which can be anything you like.
As usual there's not a lot of people to chat with, which as we all no isn't very good for a random chat site and the one person I did connect with was balls out and ready to rock, though I wasn't.
