I am almost certain that this is wrong. The restaurant's website still exists https://schmedd.lu/en/brasserie-schmedd/

I would like someone to confirm this. Ideally a picture/video of the area.

As for the other building, it is incorrectly tagged as a restaurant, and the name also seems incorrect.
However, i'm not sure the suggested name is correct, the official site mentions that it's location is Musée de la Mine Cockerill

A survey is required to know the current state here.
