something round, or that has curved lines. the last one's the most $$$, but oooh, it's pretty.

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

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?

Thanks for your reply. Here if you see the picture. There is a groove at the centre, initially i was planning to place natural stone on that, thats why made a groove. but when i was having lunch , i found not enough space for keeping food/utensils. Due to small width, and if I increase the width of table top - both sides by 3 inches, it will suit me perfect. So if I place a clear glass on top, what should I place at the central part. How to manage that groove, I am thinking about putting stone pebbles. Another option - I can place glass at the center and for sides, can place stone slabs. Again, do you think, should i fix stone over there. It will fit the groove.
