This is the location of the original Don’s Beachcomber Cafe, the forebear tiki bar that opened in Hollywood in 1934. A couple years later Ernest Raymond Beaumont Gantt opened a larger place across the street called Don the Beachcomber, then subsequently changed his name to Donn Beach.
There’s nothing to see really, and as far as I can tell there’s nothing technically at 1722 anymore. There is a condo sitting over location of the second location.
