The San Diego is a must stop attraction if you're in the city. It may seem pricey at first at about $50 a ticket but it's well worth it for the amount of animals you can see.
Don't underestimate the size of the zoo by just looking at the map... This place is HUGE! You can easily spend half a day or more here.
Plus, at the time I went, they were still expanding and adding new areas, exhibits, and animals.
