Hell, you could set up a whole build-your-taco bar if you’re feeling extra ambitious, though the options are only as good as the car owners’ tolerance for possible spills.
When you aren’t worried about whether or not the food you have can fit in a purse or oversized hoodie, the sky’s the limit.
Pizza, footlong hoagies, every type of Asian food, and whatever damn popcorn you want to pop.
My tip would be to bring a blanket or something else to enjoy the meal outside, because freedom of food choice is by far the best perk of this experience.
