Underwater View of San Francisco Bay
By A Yahoo! Contributor, 5/2/09
Very cool tunnel tanks filled with all kinds of fish from San Francisco Bay. You walk through the tunnels and shark actually swim over your head and next to you. Pretty jelly fish, too. Lots of helpful staff to answer your questions. Lots less expensive than most aquariums I've been to lately, so the 40 minutes it took to visit the exhibits was well worth the money.
