As their web site says… “The Exploratorium isn't just a museum; it's an ongoing exploration of science, art and human perception—a vast collection of online experiences that feed your curiosity.” Another key word that keeps showing up… “interactive”. Put another way… it’s a museum where everyone can be a kid and that is a good thing.
The museum is BIG (as in 100,000 square feet)… so if you have a BIG group (max seated is 1100, max standing is 3500) it can accommodate pretty much anything, but it is also divided into galleries that can be rented separately for smaller events. Many of the galleries (and combinations thereof) have great views of both the city and the Bay, plus your group can play with all of the contraptions the museum is famous for.
Note… it is a museum and so there are always some restrictions, some timing issues, and a lot of other fine print… but if you can work with that, everyone loves the place. https://www.exploratorium.edu/
