The brox zoo is better. I haven't been to Staten island Zoo since my childhood school trip. Gift shops, snack places, a petting zoo, and a nice green scenery of trees, like a forest. But parking isn't a pain-in-the-butt here. Right in a residential area. This zoo is too small, but alot of people do come. They close early. Don't forget to bring your camera.
Pros: People, animals, gift shop, indoor hands on activities
Cons: Very child oriented
