Is there a more fancy name for a "kitchen hole"?
Does English have a specific word for a hole between the kitchen and the living room that is used to get food directly to the dining table?
German has the nice Durchreiche, which approximately translates to hand-through. I am ideally looking for a nice translation of that word.
