I love these, I think a lot of it would be customizable, potential build your own stations for things.
There would be a lot of snacks, like apple slices and peanut butter or carrot sticks. Maybe even some animal crackers or teddy grams.
Definitely nuggies, mac and cheese, mini pizzas, spaghetti and meatballs, sandwiches where you can have them cut however you like, like grilled cheese and tomato soup!
Maybe a breakfast bar with cereal, waffles and pancakes (in different shapes)
Juices, milks, smoothies, milkshakes, boba, hot chocolate, (maybe a tea party room!)
Sundae bar, cupcakes, cookies, brownies, candy
I think there would need to be a lot of nostalgic comfort foods, but also atmosphere would play a huge part of it! I would love it if this became a thing
