I haven't been to the zoo since my daughter was around 6 or 7. I have visited the Sedgwick County Zoo in Wichita, the OKC Zoo, and the zoo in Topeka, Kansas. Sure they all have most of the same animals and other features, but they aren't set up the same.
The Segwick County Zoo and the zoo in Topeka both have a rainforest set up on the grounds. Neither areas at the zoos are made the same, nor do they have the same types of animals and plant life. This is a feature the OKC doesn't have. Neither of these Kansas zoos have an amphitheater which the OKC zoo has.
The OKC zoo has a YouTube page. You can go on a tour of the zoo without leaving your home.
