The Khantessa and I recently rearranged some of our furniture and other oddments. The chief result was that our former dining space--a modest throughway between the kitchen and living room--became my office, and my old office became our formal dining room.
I must say, I don't know why we didn't arrange it this way when we bought the house 22 months ago. The formal dining room is so much more peaceful and atmospheric, and almost mimics the ambience of a fine restaurant. And when it comes to dining, atmosphere really matters to me.
What are your household dining arrangements?
