Now you're just being silly.
Tell me, how would something like a giant pretzel for the table to share be any different than a couple baskets of bread? How would one cake sized cupcake (let's say serves 4) for a table be more work or take up more space than 4 individual plated desserts? Have you ever worked in a kitchen? Plated desserts take up a LOT of space as do trays and baskets full of individual rolls for bread service. They have plenty of space in the kitchens, they are literally banquet kitchens. Space is not a problem. Giant and tiny foods are most definitely something they could incorporate into the regular menu, just as it's done at a counter service restaurant at
Disneyland that has a FAR smaller kitchen and serves FAR more people daily.
