In a few words: the only free stuff/attraction (in a tourist perspective) to do Chicago. Out of that, couple of things: Animal cages are sad. Very small and any time the animals looks sad (mainly the monkeys and lion)...clearly a small space, it s not big at all as a Zoo should be! Food options are not big deal! Good things: the holiday/Christmas lights are beautiful...statue with songs...very nice!! Everything else is quite less than any other city Zoo in US.
