In our last few houses with a formal dining room we always used it but almost never as a dining room. In our current house which we built, we have a pretty formal dining room. I have used it with the chairs pulled back as a place for guests to set their potluck dishes or gifts for birthday parties or Sacrament receptions (First Communions, baptisms, etc). It’s my cake and coffee station for other parties where our kitchen table and counters are being used for the meal or other things. Right now the dining room is holding our family puzzle and some homework. It’s handy but we never eat at it. We have another table that seats 10 in our kitchen. I planned it this way when I built the house. It works well this way for us.
As other posters said, think of how you entertain. Do you regularly host any family holidays where a dining room would be handy? Do you have an outdoor area where you and others are more likely to sit? How would you use it? Because of our cold winters I knew I’d need a large indoor table or 2.
