The 7-ELEVEN in the Gold Cup photo is the Hollywood Barber College. In the current photo the Gold Cup is a Tattoo place.
In the 1947 directory, info from Martin Turnbull's site:
The Suzie-Q – 6700 Hollywood Blvd – Nightly Entertainment in Hollywood – Dining – Dancing – Cocktails – Corner Hollywood & Las Palmas.
In some online blogs it's noted as a place the Black Dahlia visited. (Is there any place she did not visit?)
I don't recall seeing any photo of The Suzie-Q.
In the 1950's the location was The Royal Room, mentioned by me before, with the Union Pacific ticket agency next door mentioned above by
Alkapone.
