Chabot is a great place to spend an afternoon. We recently took an exchange student there. The exhibits are well thought out. The cafe has good food at a reasonable price. The only negatives were that several of the interactive exhibits were broken and while the staff seems friendly enough, they didn't engage the patrons enough with the demonstrations. I thought we'd get a nice view of the bay, but the trees block the view. Many of the exhibits are geared toward older children but they seem to have hands on activities for the younger set too.
