(Spoiler: that is not my kitchen up there. That is a kitchen belonging to a person with much, much better hydrangea-cultivating abilities than I will ever have. If you ever see an alive hydrangea in a photograph on this site, please rest assured that I had nothing to do with it.)
When we were house-hunting (both times), the big thing that I really wanted - that I would not compromise on - was one of those kitchens that everyone can hang out in. And to me, that means a kitchen with a center island and a couple of bar stools. Our kitchen is sorta open - at least, it's more open than the kitchen in our last house, which could more accurately have been described as "completely and utterly isolated from the rest of the house and anyone who might be in it." But it's still missing that sort of breakfast-y hangout area that I've always fantasized about.
I can't install a *real* island in the middle of the kitchen because the space (which you can see here, in my kitchen makeover post) is too narrow, and I can't install one off to either side because there are doors in both spots - but one of those doors is a glass slider that doesn't open anyway, so I don't mind having something blocking part of it so long as that thing can be moved.
