There are quite a few aviaries like the one at Edinburgh that I know of. Not on as big a scale, but Zurich zoo has Agoutis, Grey winged trumpeter and mot mots housed together, and they have Sloth and Spangled Cothinga. they also Have the Huge Masola exhibit, but that is not an aviary as such, it's more of a biome building, but It still has an array of species, geckos, Lemurs, Madagascar crested Ibis, and like in the wild, you are not cerainly going to see some of the more elusive species like the Lemurs.
Chester also has the Mythical macaws aviary which has Azara's agouti, Red tailed amazon and Blue throated macaw. Chester also tends to put a ground dwelling species like a pheasant in an aviary with a small paseerine, turaco or pigeon.
My favourite exhibit....hmmm....... Well there is the Islands in Danger at Chester. It's brilliant. One of the Juvnile BoPs will come up to me and let me stroke his fet while he chirps away at Me. I also like the Komodo dragon enclosures. Have you noticed the Java sparrows in the original one? There are also Visayan Taricitc hornbills, which were courting when I last visited and lots of pigeons. There used to be white collared kingfisher, Palawan peacock pheasant and stella's lorikeet in here, but the kingfishers werent getting on so some are being moved to other zoos while some are staying in the zoo in the aviaries near islands in Danger. The Stella's lorikeets died out, and I don't kno what happened to the Palawan Peacock Pheasants.
But then i love The tropical realm, Realm of the red Ape and the Elephants of the asian forest. But these are all houses, is that OK, or do you want just one Exhibit?
