Having looked at the POIs imported within the UK, these all appear to duplicate existing objects. I can see no value in adding an unnamed amenity=bar or amenity=restaurant node next to a named pub.

I can see even less value in mis-tagging a bus-stop as a bar, apparently just because it had the word "Oyster" in its name.

I have reverted the remainder of the UK part of this changeset in https://www.openstreetmap.org/changeset/146070139
