I've definitely seen larger zoos and aquarium. However, this place is load with so much cuteness and the admission fee isn't bad at all. I think it's a great way to take your friends that's visiting or a date with your SO. The zoo is really small compare to other ones, but there is also the aquarium connecting to it. Me and my boyfriend stayed about 3-4 hours there. We enjoyed it. Oh we got tickets in advance in giant eagle to have $2 off! So do that, if you have time :)
