The Garden of Allah. The Cocoanut Grove. The Brown Derby and The Luau. They were the hottest places to see and be seen during the Golden Age of Hollywood, from the 1930s to the 1960s. Anyone who dined at these glamorous venues or wishes they had will thrill to the Out With the Stars exhibit, opening Saturday at the Hollywood Heritage Museum. The exhibition showcases these starry restaurants and much more from the 20th century in Los Angeles, Las Vegas and New York, with a special room devoted to World War II’s Hollywood Canteen.
