Disregard the whole thing about splitting this part of the building off -- this is accessible to pedestrians and is part of the mall. 

But it is still a bit weird with the outdoor portions like the Starbucks, because those aren't accessible from inside the mall (even though it is technically all one big building). I don't think this is a major problem since there is a separate address point right outside Starbucks to suggest an entrance, but I'll look into best practices before closing note.
