Can you give me any ideas for my 15th birthday party?

I really want to have a fun birthday party this year. My birthday is January 5th and my party will either be the 2nd or 3rd. I want my party to be guys and girls. I would prefer it not to be at my house, seeing as though I don't have a large house for all of my friends. I DON'T want to "go roller blading" or "see a movie" like a lot of teens do. I want something different and fun but not to pricey seeing that I want an extravagant 16th birthday. I love theme's something fun to. I would like my 16th birthday to be a night in paris but I have no Idea for this one. If you can give me any ideas of what I should do or a theme that would be great! I really need help with this. Please nothing childish or boring like.. "a sleepover." I've done that.
