You are standing in a kitchen walk straight at the end of the counter. Turn right from the counter and now in front of you their is a grey door. Turn left from that door. And go straight near the partitions on your right. And when you look ahead you will see a washroom in front of you just across a small hallway. And on the side of the washroom their is a closed door just giving you a hint. Go inside the washroom and as you enter the washroom you are done.
