Walk towards the bar stools in front of the bar at the kitchen counter. One you reach the bar stools, turn left and walk down the hallway, bypassing the small wall on the right that divides the room. Straight ahead you'll see a bathroom with the illuminated mirror, turn 180 degrees, facing back out towards the bar area and where you just came from. To your right is a room with a door with a small circular window in it. Walk into that room on the right. Walk one step towards the silver couch on the right, stop, you're done.
