Where is a hippie chic, artsy, soulful place to go dancing in Seattle, WA?

My best friend's 26th birthday is coming up and I want to take her out. I'm not a dancer but she is! She loves to go to clubs or anywhere she can dance. She is crazy fun! Very outgoing, loves rmb and the beetles! ha If you can picture a bohemian chick dancing to Luda then that's her. =) Where can I take her to have a good time on her Bday in or close to Seattle?
