The zoo is pretty big. I liked playing with the sting rays and walking around looking at the animals during the day. Whenever I go to Zoolights during the night, everything is asleep.
It's the usual zoo with your jungle, desert and whatever animals. There's plenty of shops and snack shops. You can go on a tour, ride the camel, go on the slides (which is really expensive because it's $3 per ride going down a slide), get up close with the giraffes and even get up close with the elephants.
Good place to take the kids and spend an entire day there. Let them look at the animals and also about them too. Bring some water and snacks so you don't have to pay for it at the zoo.
Oh... FREE PARKING.
