I'm from St. Louis and love our zoo. We wondered if it would be worth visiting the San Diego Zoo during vacation, and it was. I would say it's 2x the exhibits and animals as the St. Louis Zoo (of course the St. Louis Zoo is also free, and the San Diego Zoo is priced similar to a theme park). This year we saw construction for another large expansion. Great exhibits; especially birds. Can't beat the weather. Well worth it.
