Would you have your island set up with as an extra prep area or would be strictly for storage, with a little overhang and a few stools for quick meals?
I know you asked this to someone else but since I desperately need an island, too, I'll answer it. I'd like as much storage space as I could get out of it but it would also be important for it to give me some extra prep space. I sadly lack that in my current kitchen setup.
