A restaurant whose front door is in the north, east or south wall now has a proper outside: sidewalk around the building and road beyond it, instead of indoor wood floor.
The road markings run along the street in front of the door, and the shop-front glass sits on the wall with the door in it.
The strip of wood that showed along the outside of the walls is paved over.
The screenshot shows a randomly generated restaurant with its door in the north wall, the same one that was painted as wood in Iteration 60.
