Mason's was a restaurant located at 11500 San Vicente Boulevard in Los Angeles, California.

I used to hang out with Harry Nilsson. My husband (Morgan Mason) had a restaurant in Brentwood, California called Mason’s. He (Nilsson) used to come every single night and hang out in the bar and hold court. He was such a kind man; just wonderful. I would like to think that he very much approved of my renditions that I did of his songs.
