Love the Pittsburgh Zoo. Every visit here the staff are friendly and very helpful. I will have to say though, there has been a lot of changes made to it and frankly I don't think all of them were necessary. The Zoo itself feels smaller than before. Exhibits were taken out and not returned. The Bears for instance, totally gone. Yes there are new restaurants and eatery's but they shouldn't be the prime focus. Overall the zoo is a great time for young and old alike.
