Just to add my own observation here: some cuisines are really optimized for sharing in larger groups… certainly a lot of the regional Chinese cuisines assume many people at a table, with large (i.e. higher priced) servings. If it’s just 2 or 3 of you, you end up getting only 1 or 2 dishes, often with a lot left over.
So, this is a genius way of optimizing for that!
I totally want something like this here in Sydney.
