One of the best zoos in the world. It will take a full day or multiple visits to try to see everything you want to see. Parking is free. Annual pass is well worth it if you plan to go more than a couple of times within a year (or even in a week!). Food and drink isn't great and it is expensive although there are a lot of options. Worth taking your own food and drink. The bus tours are a good way to cover a lot of ground and get your bearings.
