I see what you're saying. I think a single-floor layout would definitely be best for this type of restaurant. I was going to suggest small, contained kitchens and no waiters, but then there wouldn't be much differentiating this idea from say a food court, or a collection of food carts. I think having sections with distinct cultural ambiances would be neat. Perhaps there could be a collection of distinct culturally-themed rooms on a single floor, each limited to basic food and drink so that they do not occupy much more space than a bar, with perhaps a small kitchen in the back at the most.
