I agree it is not one of the worst in Britain, I don't know which zoo gets that award since I myself don't take too much of an interest in Chimps (prefer gorillas and orangs). It is decent enough for the animals, but it is very unpleasing to the eye and is simply out of date compared to Chester's other exhibits (these things happen, 15-20 years down the line and Spirit (my fave at Chester) will seem out of date.
