Wild Mary's (?)
I was in Hollywood back in 1981, staying at a motel on Hollywood Blvd. I would spend most of my time on Hollywood Blvd. and I never once saw the giant lady over the massage parlor storefront they called Wild Marys. I think that must've been filmed at a studio backlot and not in Hollywood.
In the book/novel they said it was on Hollywood Blvd, however.
