Eat in the hat

Here's a vintage postcard photo of the Brown Derby Cafe on Wilshire Blvd. near Rodeo Drive in Beverly Hills. It was 28 feet in diameter and 17½ feet high.
My first father-in-law, who served with distinction in the 144th Field Artillery Group of the U.S. Army, was an avid postcard collector. He bought picture postcards as souvenirs wherever he traveled in the 1940s. This one is circa 1940.
The sign on the roof says, "Eat in the hat."
