also, the gorgeous set would look nice for a bar; you could add things like pool tables there, too.
add mannequins dressed like chefs, a bartender, waitress, cashier, etc.
For the tea room, you can use the tea room wall with tea tables, cushions (can be customized to look cute), tea tansu, tokonoma, tea vase, tea set, etc etc. I guess that's if you want a more traditional looking tea room.
otherwise olivetree's list is really nice and includes a lot of what I would suggest ^^
