Visited the zoo as part of the CityPass ticket booklet I bought just to see the pandas and polar bears.
Coming from LA, those are the only two animals I cared to see and boy were they cute. There are two pandas, one of sleeping and one was munching on his bamboo dinner. I think there were the polar bears, one sleeping right next to the window, one sprawled on the grass, and one lounging in the water. They were the cutest bears and living in a very large exhibit.
This zoo is very extensive and you will need the whole day to see and explore everything. The exhibits cover alot of ground and it's quite a trek to get from place to place.
This zoo is located miles away from downtown but worth the drive if you have the time. Regular admission price is a bit steep, so I wouldn't go if it wasn't at a discount. Parking is an also an additional $12.
