Can we take in food

Yes you can. I take food and drinks in everytime I go. I'm an annual pass holder so I am there alot.

The park does not intentionally let you bring food and drinks in. But if you are discrete and carry snacks, small drinks and snacks in a backpack that will work. They scan backpacks at security checkpoint but they do no search them.

yes

If you have dietary requirements you can bring food.

Yes, you can take food and drinks.

I believe that some type of food are allowed, like snacks or water, but sandwiches or something like that not.

No

Ofcourse yes, dried food. We did and it helped us a lot.
