Restaurant City - A online game of Facebook by Playfish
Some interesting things are found when playing the game:
Floating nameplate - you can place the nameplate of the restaurant above the building making it floating on the air.
Serving behind the chair - waiter can serve meal and clean table behind the chair even just reaching the corner.
No one need to clean the toilet - just pull the dirty toilet to the inventory and then pull it back in place, it will be cleaned.
Waiting chair - you can place some chairs without table, so customers can wait there until there is a vacant table.
