Food for thought, and bare with me if it doesn't make sense..but what if they are working on a hotel for that plot, and that's why we aren't seeing the typical construction walls but instead, the black fencing with the trees?
It would certainly be a difference from previous instances of construction walls, and could explain why, as it would be a much larger project in scope and scale.
Wishful thinking, I know, but I have to wonder why they didn't keep the other walls, if it would've been something we would've thought to be a dining concept?
