I have to add my vote to timber. Glass, in my opinion, tend to leech spaces of warmth and with timber tables available to suit so many design styles and to suit a range of budgets, As Wild River Store rightly pointed out "Timber develops character" over time and so it begs the question why anyone would look further than timber?

It might be worth while to consider the rest of the space also. Your breakfast bar/kitchen is located quiet closely to your dining table so depending on your kitchen space (apologies, I can't see too much of your kitchen from the photo) you might want to think about the overall style you want to achieve for you entire open plan space, and select pendants that would work for both your kitchen and dining. This is a project I worked on recently that shows how two different types of pendants can work harmoniously in the one space that is most similar to your kitchen and dining set up. Keep us posted on what you decide!

We finished our antique island bench, which was originally the haberdashery counter from David Jones in Newcastle, with a burnishing oil. The surface proudly bears the markers of it's history as the timber was too soft and thin to strip back any further than we have, but the burnishing process has protected it from every day wear and tear including water spills and the rough and tumble that our four boys dish out to every piece of furniture in the house, it also gives it a beautiful shine. We have finished our dining room table the same way. Kitchen dresser and the sides of the island bench that don't get the same use are finished with beeswax.

What a beautiful room, table is great, I love transparent furniture also it could work well with your room, I can imagine it with your table but a more luxe look could be stainless to blend with benchtops or leather or be brave and mix it up for a more contemporary look, depends on the style you are after, fab room
