ahhhh,,, I think you know what to do man. The cards are lined up, my friend. You have a great oppurtunity here!!! Don't over analyze this. After having a few drinks, ask her is she wants to dance. Make her laugh, flirt, let her know that you are into her. Then if it feels right go in for maybe a kiss? This is a judgement call.

The one bad thing about clubs is that you cant hear anything. Maybe, after getting your groove on for awhile, go to the bar and talk to her one on one. Dont say you like her or any bs like that. Ask her if she wants to get some dinner sometime, or go catcha a flick. She will get the hint. Once again, dont over think this one. Im sure you will know what to do when you are there.
