Go in the doorway straight ahead and stop to the left of the grand table.
Turn to the right and walk down the table towards the tall lamp in the corner of the room. Go around the end of the table then walk directly out the the end of the large table in the middle of the room. Once you get to the end of the table, you will be beside two black chairs. Walk to the middle of the hallway made by the two large tables in the middle of the room and stop.
Walk to the right of the table and chairs and left between the two supports. Walk into the main room to the left of the table and chairs and stop just past the black chair.
