Are outside food or drinks allowed?

Yes, they also have some to buy inside.

Yes they are.

Yes

They allow your own food. The other people had season passes. Just a very chill and beautiful little zoo.

We took in, a water bottle. But, there we're alot of people at the entrance. No one checked us, we even seen a few people, not even pay, they just walked through. We ate & bought food there, it's not real expensive. There's a park in the same lot & a big pond with duck's (take some bread & feed the duck's, if you want). So you can actually eat there & then go to the zoo. I'm pretty sure they don't allow outside food.

Thanks everyone! :)
