Looking For Ideas For My Friends 21st Birthday!

Hey Everyone! I`m looking for some ideas for my friend Lauren`s 21st. Her birthday is in 20 days soo im pressured w/ time.She`s already been out to every bar/ club in our city. So I want to do something different but still fun and hopefully something memorable because she really isnt that excited for her 21st since she has been goin out for the past year or so. I dont think she is interested in having a party. So maybe some suggestions on different things we can do while we are out at the bars or clubs to make it fun and unique ?? we are maybe thinkin about getting a limo, maybe going to dinner then out not real sure yet... But I want to suprise her on how much fun she will have! soo if you can help please do so.....
