I found a third photo of the Warner Bros., KFWB, Aldo's, Coffee Dan's location on Hollywood Blvd. This one is dated 1956. It was mis-marked as taken west on Hollywood Blvd. from Vine Street instead of Cahuenga, which might be why I overlooked it before.

A closer look:
The CD for 1956 lists these businesses in that strip, from right to left:
6405 Hollywood Blvd.: Coffee Dan's
6407 Hollywood Blvd.: Karp's Men's Wear
6409 Hollywood Blvd.: Foundation Health Foods
6411 Hollywood Blvd. (Levinson Bldg.) the second floor offices were occupied
............................. by the Jack Linder Agency, Cunocar Accounting Services,
............................. A1 Music Arrangers and Velasco's Talent Workshop
6413 Hollywood Blvd.: Aldo's
6415 Hollywood Blvd.: Thom McAnn Shoe Store
6417 Hollywood Blvd.: My Desire Cocktail Lounge (Larry Potter)
6419 Hollywood Blvd.: KFWB Broadcasting Corporation
To the right of Coffee Dan's at 6401 Hollywood Blvd. is Florsheim Shoe Shops
which probably accounts for the FLO on the billboard at top right (and see below).
