I like it. I would keep it. Not a real good re use for it.

Well, you have to satisfy your own taste, but I think it's great-looking granite, and goes well with the cabinets and the tile backsplash. If I were spending money in that kitchen, I would use it to put in a more interesting color of floor tile, or a cork floor that would complement the cabinets and granite. It's really quite a clean, classy, and refined kitchen. And you might have an entirely different feeling about that granite if you have a floor with some pizzazz.

The granite looks great. How about a lively backsplash, maybe that would change the look towards the direction you want to go.

Dark soapstone would be beautiful....but of course you will need to also update backsplash. If the granite can be saved without cracking it during removal...I think the outdoor cooking area idea is great.
What style overall are you looking to achieve?
I totally understand you want to make it your own...not crazy about the currant granite myself!

We're looking for a more contemporary look with greys, whites, blues. None of which really match the granite :/

Cobalt blue in some of the accents would be an awesome touch!

Yes, I like your style.

Shoji white by Benjamin Moore is a great paint color to use on the walls...with a subway backsplash...that way the soapstone will really pop. Be carful with the type of blue you use because it can start looking country really quick...
Worldly gray by Benjamin Moore would work on walls too...it is a very light gray almost a white gray.

Thanks for your advice!
