Do you need a dining space? I might place a dining table where the L sofa and table are now and move that to the other end with television and a couple of chairs near the fireplace.

Thanks, nice thought but kitchen has a nice long island, so we don’t really want a dining table.

If you don't want a dining table you'll have two seating areas which is fine if you think you'll use them. Placing furniture in front of the fireplace is problematic because you have to walk by it to get to the other seating area, but two chairs with an end table between them could work. If you don't picture yourself wanting to sit in front of the fireplace, just leave the space empty. Space is usually better than an overstuffed look.

a dining table would be such a gracious addition for entertaining guests, card games, puzzles, homework etc

I kind of like the fact that there is just open space without the dining table. But, I'll have to think again about the dining table. I was more thinking of another sofa in the empty protion... but, I'm a litttle cluess with it. I'll also see if I can get a few photos to post.
