Well...this was an absolutely incredible zoo. Got to see all of your recommendations, except the children's zoo (thanks to a violent thunderstorm.)
I'll follow up with more detailed thoughts, but the short version is that I think STL has the best attention to detail of any zoo I've been to. They mix a strong collection of unusual creatures with some of the best exhibits I've seen for more common species. Probably the best elephant exhibit I've been to, for instance, and the Sichuan takin exhibit could have just been a yard, but the rocks in the middle show off their climbing ability. Just great.
The penguin exhibit, though, was definitely the highlight. I wasn't sure why there was a line, or a sign on the door that said "Please don't touch the penguins," and then I quickly realized that it's because it's an open-air exhibit and the penguins are right there in front of your face. Really breathtaking, and one of my favorite exhibits now in any zoo.
