Family Outling Lunch

I have planned our first family outling since the COVID restrictions have been lifted where I live. My bf & I are taking our kids to the zoo tomorrow. I want to pack a nice lunch for us to enjoy. I need some advice on what to pack as I don’t know if they have any coolers. I was thinking turkey & cheese sandwich or roll ups (i’m not sure about e bread - suggestions??) , pasta salad, goldfish or trial mix and fruit cups. Of course lots of water. Nice comments only plz! Thanks moms
