You must take it done
You can eat in different places in the park but you cannot cook there, they have a camping area that is on one side of the park there if it is allowed, I imagine cooking because you can spend days there.
If there are tables to eat as a family, but you have to take things, there is also a restaurant, you can say that they give you the things and eat them where the outdoor tables are, BBQ no
Roasts are not allowed. But there are tables for pinic.
There are picnic tables but BBQ is not allowed
They do not accept BBQ but there are tables for the picnic
You have to bring the cooked hamburgers, they do not allow you to do BBQ, if there are tables to sit and enjoy the outdoors
I did not see there any place to have picnics or the like. So I don't think it is possible.
