There are lots on snack and drink vendors and a sit down restaurant inside the zoo. You can take water bottles and limited snacks. No coolers. We take a bookbag with snacks and drinks and have no prblems. Have fun!
They have snack stands and a restaurant. I don't know about outside food.
Typically outside food is not allowed. But, there is a place right outside near the river that you can picnic. Also, small snacks and such are no big deal.
