For the basement bar, first decide whether you want a walk-up bar (counter against the wall) or an island/peninsula bar. If you don't have the room or don't want to give up the room, a walk-up bar is a good alternative. Many expensive homes will have this type in the family room.
I built a glass block bar with a mahogany top and mahogany cabinets. My bro-in-law did a simple 2x4 frame with a paneled front.
