I am sad to go here since Willie B died, he was part of this zoo for as long as I can remember.
The Panda exhibit is nice. Go later on a weekday and you can actually see it without having to peek around a zillion school kids. The schools in the area that do field trips try to be out of there by 1 pm so go around then.
It doesn't seem from the street that there would be enough room for a zoo where it is located, but there is plenty without it being crowded. The parking can get confusing, and then you walk down a LARGE hill. So anyone with trouble walking will need to be let off at the gate.
I like that the flamingos are the first thing you see, the only change I would make is get rid of the reptiles and get some otter.
