Yes, JudyG that's exactly the way people were using the taller table. Sort of a café look, or casual bar setting. One home had a beautiful huge kitchen all done in white with dark wood floors and RH style fixtures and hardware. Where you would normally think would be a traditional dining room, they had made it up with a large high table and 6 barstools. It almost looked like an extension of the island. Another one was in a very open and light kitchen. It was smaller and where you might think of putting a breakfast nook they had a round café-style table with four barstools. I liked it because it gave a more casual appearance. If people were sitting at them, they were on the same level as those working in the kitchen. Almost like a bar at the island for that effect, but with some separation.

If I am having trouble finding a rectangle glass top table I usually order the glass from a local (to the location of my Client) glass shop and then the base from one of my furniture vendors. a dark table with your light chairs should not feel dark given that it is in a room with what looks to be lots of light with the large glass door and side window. I do think the glass would be perfect for the area. What size table are you thinking will fit the best in the space and for your needs?

#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

i must say your polls are interesting and gives lot of great ideas.....keep it up!!
