@mhatres, Consider yourself lucky today. I had a student designer who wanted to see how a design can be made with a little information. I took your floorplan for an example and made these designs for you. Hope you liked them!

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.

One option, I would get a very large rug so that all the chair legs and at least one corner of the sofa is on the rug. I think I would also bring the table set away from the window a little more. I think there is enough space to place the two-seater opposite the table in front of the window. or bring the table forward toward the kitchen ....... With the sofa centered to the large window. They probably will not be opposite each other, but at an angle which is still ok. They might seem more functional for the table set to be closer to the kitchen. Another option is two rugs in wide runners. Creating a walkway through the center of the room. Still thinking the sofa center of the right window. Just some ideas :-)

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?
