How about a bar version of golf? Instead of a huge 18 hole course, just have 6 holes, all arrayed around the same green on top of a table. Since swinging the golf clubs would be dangerous in a crowded bar, you might need a way of hitting the ball that is more direct. The small size of the green would make play a little too easy, so you could add some mini-golf style obstacles. Or, better yet, use the golf ball to strike a target ball to hit it into the hole.
