Somewhere between 7 and 8, I think (couldn't stomach the rest of the game)....
I'm not sure what you mean about the doors, though.... the outer door wasn't locked (but it is thoroughly booby-trapped with wind-chimes), and leads to a little waiting room - first time in, the girl greeted me quickly, and said they were all busy... second time, she took me to the session rooms behind a second door (not sure if that was locked, but I think so)....
Don't know if that is good or bad... but then, it IS the Danforth, so....
