I want to put a table and chairs there but it looks like the builders installed the light fixture off centered.
I suspect they placed it off center to allow for a walking space between the dining table and the island.
If you don't care for the fixture -- and I don't either, so plain, doesn't coordinate with the island pendants -- change it, but I would not change the location. Furthermore, if you change the location, you'll probably have to "swag it", and I doubt that's the look for which you're searching.
I recommend moving in and actually placing your dining furniture to determine the scale and room needed.
Good advice. Go ahead and place your existing table ... then you can judge whether you need something larger /smaller /different shape.
Do Nothing now. That "dining space " is too small to be considered one, unless a table for two under the window.
Oh, come on. It's not a huge space, but it can certainly hold more than a two-top.

Love the front layout except for the wood accents above window
