"Finger Food"? I have heard of it.
Did the Elves know Hobbits well enough to invite them on dinners?
Another question that has never been answered to me. What about wine? Wine contains alcohol. Did the Hobbits, Dwarves and Men really drink "alcohol"? Alcohol is prepared chemically, in Labs. Did people in Middle-Earth prepare it chemically? How?
