It's a very beautiful and well maintained zoo. The animal appear to be treated with good care. There are toilets and tap water every here and there.
It could be better if there wasn't differences in the entrance tickets. The general admission doesn't allow access to the butterfly gardens, gorilla's den among others. The full experience would cost $17,00 more.
But it's a very nice place to go at a walking distance from the subway station.
