The popular Hollywood & Vine restaurant evokes an early Hollywood feel to it and the architecture of the building certainly gives that feeling. It has a unique look to it and inside, is a very sparse "spartan" look to the place. Imagineers referenced a bygone era when they worked on this restaurant to give some diversity to the sort of buildings that were being developed for the Disney-MGM Studios.
Hollywood & Vine is meant to recall the many cafeterias that were common place in the 1930's, 1940's and 1950's. Before fast food became the preferred means of getting food quickly, cafeterias were where Americans went out for a bit to eat when they didn't have the time (or money) for a more formal sit down restaurant. Cafeterias were most popular in New York, although some did manage to make their way to Hollywood, despite never being quite as popular as their east coast brethren.
Imagineers drew upon one specific cafeteria for Hollywood & Vine, a popular cafeteria at 1725 North Vine, which was located near Hollywood Boulevard. This cafeteria was also once the Hollywood Branch Post Office and unfortunately closed in the 1980s and burned down. Inside the restaurant, Imagineers decorated the walls with murals and photographs of "old Hollywood".
