Chances are, if you're a kid in the area, you've heard of the Children's Discovery Museum of San Jose. It's a fun and educational activity center that succeeds in appealing to adults as well. Toddlers are welcome here, and it's a great place to plan a birthday party for a young one. Call ahead or check the website for availabilities regarding private functions. There's also information on the website about lectures and other rotating events held here.
