What are some exciting things for teenagers to do in San Francisco?

OK so Im about to have my 14th birthday party.

For the past few years, ive done it in my relatives big house in the city. I bring about 10 friends and we do some fun stuff around san fran. In the past we've gone to shopping down on market, we walk to the golden gate bridge, we get our nails done on Scott (off of union), we go to crissy field, we go to a fancy dinner, we do to the lion street steps, and have a massive slumber party.
