PITtSBuRGH ZOo?

I am coming from New Philidelphia Ohio to the Pittsburgh zoo. It is going to be 2 kids. ages 4 and 5. And 2 adults. We were just curious if anyone knew how much it would be like spending cash? I already checked out admission and all the necceseties, we were just curious how much would be sufficient ya know to like eat there instead of packing and maybe buying the kids something.......ya know, just a day at the zoo. Thanx in advance for those who anwer.PITtSBuRGH ZOo?
The prices are ok, maybe a bit more than I'd like but I'm a cheap student. One thing that would save you money is to bring drinks, typically that's where they overcharge you the most. I imagine most foods on the menu, like hamburgers, chicken tenders, and things like that are $4-6. I wish I could remember better how much I payed last time I was there.PITtSBuRGH ZOo?
Personally I've never been there, but I would assume that they prices would be the same as like at any other zoo, amusement park, or any outdoor entertainment. I would say be prepared to spend somewhere around $10 for each person per meal.
