Does anyone know how Mozart's Coffee Roaster was able to acquire the "Loft" area?

It’s been a while since I’ve been to Mozart, and it seems that they’ve expanded a loft seating area on the left side of the upper deck. I don’t remember it being there (last time there being a wooden staircase to the bottom deck and a wall to where the loft door is now). I’m curious if anyone knows the history behind that–was it space from the adjacent building that Mozart acquired? Or was it kinda there but was never put to use?
