This particular exhibit has glass everywhere, and is of a high quality. There are 3 outdoor habitats (one glass, one mesh and one wide open) and 3 indoor habitats, with a group of chimps and gorillas having one each. The third enclosure can be used by either ape, on a rotational basis. Overall it is one of the better great ape complexes in North America, and by far the best set of exhibits at the Lincoln Park Zoo.
The entire Regenstein Center for African Apes has 6 habitats (3 indoors and 3 outdoors) and perhaps only the Bronx, Woodland Park, San Diego, Atlanta and Disney's Animal Kingdom have better gorilla habitats. I have not been to the Louisville Zoo, but that could be another contender...
