My husband is a carpenter, so I know I'd get that wine rack out of there and put a few shelves. Books, stacking cups, whatever! I might back the shelving with a child-safe mirror too! Another idea is to close off the wine rack and place a chalkboard or drawing surface there. If your island is/will be custom, very often you can switch out the wine feature for shelves. The end of my brothers' island has a space for a microwave, and cookbooks.
