Zoo is a great place. Its fun, entertaining and educational and expensive.
Tips:
Bring water-lots of it-very expensive @ zoo
Bring a stroller or wagon for kids as you have to walk a lot and they do get tired.
Bring lunch for yourself as again, expensive at the zoo
Go against the crowds as it will give you a better POV on animals instead of pushing through people to see the animal on exhibit
