What are good things to do in San Francisco?

So i’m going on a trip with my boyfriend and my sister and her boyfriend whom is 10 years older than me. So far we’re going to Japantown, Museum of Science, and Coit Tower.. fucking not enough! We don’t want to go to Fisherman’s Wharf or Ghirardelli Square.. pretty much the main places we are avoiding.. any fun things to do on October 16? :[ Help me..
