Callahan's Drive-In Hot Streamlined Moderne Neon, 1937

From Hollywood Hotel (1937)
IMDB-The drive-in restaurant where Dick Powell's character works is called "Callahans" in the film. The actual coffee shop in Hollywood was called "Carpenter's" and was located at the southeast corner of Sunset and Vine Streets. It was one of the earliest "drive-in" restaurants in the U.S. The uniform worn is based on the actual uniforms the mostly male waiters wore. They were based on the uniforms that service station attendants wore. The reason for this new type of restaurant was to cater to the new younger movie star who wanted to be seen in their expensive automobiles. The restaurant was open all night.
