A very cool place to spend half your day in SF. My 9 year old son loves this place. The hlass enclosed ecosystem is very unique and the butterflies, birds, and bugs are really awesome. The aquarium is pretty impressive with some rare species and the planetarium show is cool although it is kind of a lecture on our existence. Thoroughly enjoyed our visit and saved $ through our SF City Pass.
