You begin behind a bar in a small wine-keeping area. Move forward, slightly to the right, towards that white door that's still closed. Not the open one. Once you're in front of that white door, look to your right. You should see a movie room of sorts with a projector on the opposite wall to the open doors you're looking through. Step inside and move along the right side of the seating. From the right side of the leather armchairs on the second tier, move directly in front of the screen. Once you are directly and rudely in front of the screen, and you can see a Braveheart poster to your left, and a Goodfellas poster to your right, you're in the right place, which is sort of the wrong place, because you're right in front of the screen. Anyways, you're done though.
