We have been to the zoo a couple of time and each time was great! They have a wide variety of animals and the layout takes you through each exhibit nicely. We were able to spend several hours here each time we went.
There are plenty of places to sit and enjoy the day, or take a break from all the walking. There are a few places to eat throughout and considering other zoos / museums the prices aren't bad.
We don't have kids, but we still enjoyed all the things to see, and plan to take my neice and nephew here if / when they come to visit from the East coast. I think that they would really enjoy being here.
Overall: A
Great place to kill a few hours and enjoy animals!
