Earlier quoted context omitted.
What? That's simply not true, I've traveled through almost all of Europe and even lived in some of those places and nowhere it was "normal" to get 2-3 servings.
In Eastern Europe you often would get an entree (soup or salad), main dish and dessert.
But these are not "servings" as the OP was talking about, i.e. for the same dish (main course) that you would get 2-3 servings, something we don't do normally in Europe (perhaps only in big celebrations like Christmas).
