Here's an idea for a small bar in a corner that you could close off with beautiful draperies. The second photo shows a pretty bar cart which could hold the necessary items, and the third photo is of a simpler butler's tray.

I was looking at some mind-boggling $ lighting when we built. The designer said to buy what I loved and just put builder grade stuff everywhere else. That is food for thought. But what I found once I had a glass of wine or two and started looking online was that there is really wonderful lighting available that doesn't cost a body part. Also found a lighting store in a nearby city that has a huge sale every August. Got some great stuff there.

Seems weird not to incorporate it into the design -- I'm all about having things "look intentional" rather than working around them later. Like could the island have connected to this, rather than extending past it? or been L-shaped, so there's room for an extra stool, and also a wall cabinet? Anyway, hard to discuss that in the abstract without kitchen plans. I'm with miacometlady's original advice to not worry about it right now, and decide how to deal with it once the bulk of your kitchen is in place. You might find that you hardly notice it, with all the beautiful new finishes, or it might seem obvious to put some stainless or glass shelves there, or maybe simple is best and one simple hanging picture does the job. Don't stress about it until After. :)
