How about citing the physical location of unhelpful addresses? Ex: Rockefeller Center in NY or Penn Center in Phila. Some listings have street grid/mail address others don't have street names, numbers to help navigate.

Identifying 30 Rockefeller Center as GE Building, but even Wikipedia doesn't specify its site between 5th Avenue and Avenue of the Americas/6th Avenue near 50th Street. You do get LAT/LONG however if you're orienteering. . .
