I think I've concluded the same. Not sure if the door in the wall is still moveable? Doesn't look like it leads anywhere though.

There's a gate next to Nine Lives, but I suppose it's more of a service entrance for the store.

Do you perhaps have some idea what the yard is used for? (I assume I am looking at an empty area between the buildings.)

Also, on Esri, it looks like this building has been replaced by a smaller, rectangular building (dark grey). Could be permanent, maybe not.
