After travelling to Japan I was pretty amazed at how everything was very similar to advertising. It seems that food on the packaging is very similar to the actual food sold.
It is illegal for the food not to appear to look the same as the food shown on pakaging.
So how to fast food outlets get away with this in Australia, most fast food providers seel food that does not appear like the photo promoting the product, and i belive they use all sorts of props and take hours to make 1 photo, maybe marketing people have a bit to answer on this point.
