Can you bring food in the zoo?

Yes

I'm not sure. The zoo park rules are on their website.

Yes you can

I had a rolling cooler with drinks and food... had no issues.

Yes you can bring a back pack with snacks and drinks, no coolers tho.

Yes u can! We bring a whole rolling cooler with drinks, snacks and sandwhiches!

Yes you can bring snacks and drinks in a bag, but I don't think you can bring a cooler.
