Can you bring food and water in for yourself

Yes you can take food and drinks in

I agree with Ysela Rosales. The website for the zoo does not mention any restrictions on bringing in items but i would agree on the not taking glass bottles or alcohol or straws.

You can take food or drinks in. You can't take alcohol, glass bottles or straws. If you have a straw they will exchange it for a paper straw. You can't take in food to feed the animals but you are welcome to bring in snacks or lunches.

They do allow coolers for water and food

We took bottled water and it was fine.

I don't think you're supposed to but ive never had anybody say anything to me about it
