Yes I can see why you're challenged with this space. What about putting the dining table in the space by the hutch, and making the dining room into a proper sitting room? You could put a sofa against the mirrored wall and add a couple of comfortable chairs, end tables, lamps, etc. Can you remove a leaf from your table and make it fit four chairs? Then you could expand it when you have company. How often are you fine-dining here? If it's mostly for show, then I'd shrink it for every day.
