Zoo Miami no drinks or food?

Hi everyone! I’m taking my family to the zoo tomorrow and saw that food and drinks aren’t allowed inside. Does that include water? Also, are snacks considered different from food?

Just trying to be prepared and figure out what we can bring. I’m planning to leave a cooler with some Publix subs in the trunk since I read there’s a picnic area outside. One more thing—how easy is it to go in and out of the zoo during the day? Thanks in advance for any tips!
