For now, I am replacing by "building=museum"

The information for this tag said "Building of an unspecific type, used when someone is unable or unwilling to tag it more specifically. It is typically used when someone wants to record presence of a building, without tagging further detail." After reading that, I deleted the tag since I added the tourism=museum tag and I thought since I was adding "further detail" the tag was no longer needed. Fine either way.

It's written on their menu. The existing number online is outdated. Feel free to call to verify during their open hours

Got it, thank you
