Small Sweet Sixteen Ideas?

Ok. so my sweet sixteen is coming up and im trying to think of things to do. the party will have around 5 or so people cause i want it to be small and so far i have cupcake decortaing, 90's themed music and movies, and dinner at a restaurant, but i need an activity. my friend did nails for hers so thats out and another did a mall scavenger hunt and my other friend is gonna have a tea party type thing. i was thinking of doing something little kid themed like build a bear or something like that. but i would like other ideas. i live around san francisco so if that helps with any ideas i would really appreciate it! thanks!
