According to the Park Rules and Regulations, as long as it doesn't contain marijuana, alcohol, or in a glass container, you can take it in (although they probably also frown on other illegal substances)
You can take in any kind of food, since nowadays people have allergies to everything. All drinks, food, snacks and small coolers (like on the bottom of a stroller) can go. Like mentioned above, no illegal substances or alcohol is permitted
