This Dollhouse screencap contains
diner and brasserie.
There might also be
woonkamer, zitkamer, voorkamer, salon, massagesalon, bistro, and familiekamer.
They built the set first! I can't believe that vos, fox signed off on the set building before they had even seen the script, it is a beautiful set though.
