Hello, and welcome to OSM.

Thanks for spotting that this caterer has moved.

However, I must inform you that the way you edited the map yourself is incorrect.

I will try to explain here.

You typed an address on this restaurant without changing its location.  As a consequence, we now have a place that says that "346 Avenue Georges Henri" is located in this part of Etterbeek.  This is obviously wrong and is someone looks for an address on Georges Henri they will get a location here as a result.  It damages the reputation of OSM.  Please don’t do this.

The correct way is to remove the tags on the node on the former location and add them on a node on the new location.

I fixed your edit.  We had a vacant shop in the new building, which we could re-use.

Have a nice day.
