This is the Park Plaza Hotel - which started out as the Los Angeles Elks Club Lodge. It was built in 1922 - the architects were Alexander Curlett and Claude Beelman. It's at 607 South Park View Street, overlooking MacArthur Park. It's massive, as this conventional view shows. It's a fancy hotel now - see their website, Park Plaza Hotel. And note the history - "vaulted ceilings in the lobby, three ballroom-type halls, and other recently restored grand spaces. Upstairs, however, the nine-story building was filled with residential hotel rooms (the tenants have recently been evicted, as the restoration of the building is continuing on the upper floors). These were the hotel rooms for the film Barton Fink. Other films that have used the Park Plaza include The Mask, Chaplin, Nixon, Fisher King, Wild at Heart, Bugsy, and The Bodyguard."
Be that as it may, you just have to love the detailing.
