I also don't think this museum is located inside the Ghiradelli ice cream shop. I can't find more information about a "California Crafts Museum" in GNIS (through https://edits.nationalmap.gov/apps/gaz-domestic/public/search/names, though this may be the wrong way to look it up). Maybe it's best to delete the node or use the "was:" prefix (https://wiki.openstreetmap.org/wiki/Key:was:)?
