Havent been to the Bronx but its not a zoo.
Its has a safari ride and a walk by lion and tigers and such but that is a very small piece of the park.
The larger park has a roller coast, a water raft ride, some shows, a going back in time dark ride, a carnival type area, a dinosaur play area for kids, and finally the BEST counter service in all of Disney.
PS- Some people don't like it and others think its the best park. Usually you could hop parks after this since it closes earlier than any other park.
AK I think is something you would want to do if you haven't been in 10 years, you likely didn't even go on Expedition Everest previously? Not sure when it opened.
