We were in that area Saturday just to check it out. The entire area has what looks to be a permanent wall. Which I doubt it will be because the only corridor next to the wall is narrow now.
I do recall seeing a sign telling guests a temporary place to grab food was at such and such a place. Didn't pay that much attention to it, obviously.
And I saw guests walk through the lobby area and out the other side. I assumed the temporary place is in another building, off to the right from the check in area.
No way to be a lookie lou in the construction area due to the solid wall.
