After a debate with @Timmiegun I have voted Wroclaw despite him trying to convince me otherwise. Burger's Ocean, Mangrove, and Bush are great for their species but it simply does not outmatch the amount and variety of taxa held at Wroclaw. Wroclaw has great exhibits too and their reptile collection is phenomenal. The aquariums in the Afrykarium look great too. This was very close and Wroclaw only won by a tiny fraction but it has my vote. Sorry Burger's.
