I like the small primate exhibits at Mogo as they are outdoors, which is amazing to see from the perspective of a North American zoo nerd. Also, the enclosures are well-planted and the glass allows visitors to get extremely close to the monkeys.
The thing I liked especially about these new ones was the chance to see the whole exhibit, since the rest of Mogo's small monkey exhibits you only see through the windows at eye-level. It was really nice to see them run from the top to the bottom and back again.
