This is the alleyway that leads back out to the street from the tailors work room. To the near bottom right is the bright green collander containing washed vegetables, about to be cooked on the stove just out of the picture to the right.
Above the vegetables is the sink, containing dirty dishes. The light from the room on the left of the picture is the restroom. And just to the right of the restroom you can see the back of a neighbor with an apron leaning over and cooking on her stove.
