I want to incorporate/fuse this idea with the basic principles of a steamer chest or carpenter's toolbox. Have the big drawer that slid out open outward to create an L-shape with fold up legs to support it and staircase trays open up to create shelves. Boom! full size bar.
I managed to incorporate 'taste' into our bedroom by converting one of our armories into a mini-breakfast bar. It has everything we need for a quick breakfast-in-bed - a small refrigerator, a microwave and, of course, coffee & tea to get us going!
