Bathrooms are now rooms you build. Any area closed off by walls, with a door, a toilet, a sink and a trash can, becomes a bathroom, and you can build as many as you like.
Doors, toilets, sinks and trash cans can now be bought in the editor.
In edit mode each bathroom is tinted green when it works, or red with a list of what's missing, such as "needs a sink" or "needs a door".
Guests pick the bathroom with the shortest line, and each bathroom keeps its own line, mess and trash can.
If you break a bathroom while someone is using it, guests head back to their tables and the busboy drops the job. The chore comes back once the room works again.
A messy bathroom now leaves a dirty patch on the floor outside its door, which fades after half a minute.
The default restaurant plays exactly as before: over 40 games of 15 minutes each, about 64 guests served and 5% lost.
The clip shows a bathroom being built in the kitchen: walls, a door, then the toilet, sink and trash can. The red list shrinks until the room turns green.
