Here are some specific lighting looks, and some ideas on how we could use it?
I thought the above image could work nicely for the Inn Room. The colors aren't spot on, but I like some of the use of shadow, it gives a dingy feeling to the room.
The above two images use a high back-light which I think could be used as an interesting and distinguishing effect for the Inn Room. 
Here is another possibility for the Inn room, I'm not as intrigued by it, but it is certainly a striking image. Even if we don't use it for the Inn, it could be striking to show similar shadows for the drunken binge.
Here is an interesting feel that I thought might work for the Mayors office. This image also uses a strong window GOBO which is worth considering for the Inn. Do we want to use a sharp Window as shown above? Or an implied window using directional lighting?
