Can you bring food

Food and drinks in reasonable quantities are good to go

Yes you are allowed to bring food but if you bring drinks they cant be in a glass cup or something or else they will take it away.

They dont take away food luckily, but drinks must not be in glass containers or they will confiscate it. They also provide lockers and a picnic area outside of the park.

Yes! They do not take away any food. I dont think you can bring your own alcohol though.
