Still think the door to the turbolift should be further forward.
Here is my butchering of the photo to fill in details blocked by spock's big head. I can't tell it's exact relation to the stuff on the left because of the glass stuff, but on the right it appears to be recessed.
I broke the pic into five peices to better line things up.
As for the glass box on the right of the Hostess (her left), it doesn't even look like it goes all the way to the floor, and I can't see anything supporting it.
...Maybe it floats...?
