Mysore Zoo is just awesome, variety of animals, birds... just wow.Best attraction for me was Kangaroo, I would never have believed that we can find Kangaroos in Indian Zoo but It was a lifetime experience.
There is an Ape and trust me, it looks lot like a human being.Overall wow but make sure to hire battery car/bus if you are with aged people since park is very big so it will be tough for them to walk. I did the same for my parents.
Thanks
