This picture gives the "waitress perspective." It's taken from behind the counter, looking out towards the station lobby. Everything's original, including the cork on the far wall, which was made from recycled corncobs. And those tres deco objects on the wall are speakers, so that patrons could hear announcements for train departures.
Now the Harvey House is only used in movies (think of the police station in Bladerunner) and for private parties.
A Harvey House fan site has some pictures of how it looked during the operational years. (Scroll down to find Los Angeles alphabetically in the California list.) "Legends of America" maintains an extensive history of the Harvey House restaurants, with a section on the Los Angeles Union Station (again, you must scroll down to it).
The picture above right shows the tooled leather partitions, a bit of the bright floor, and a wood and tile wait-station. The original wall tiles are in the background--if you look close, you can see the parrots.
The last picture is of the bar, hidden away in a room off to the side, its copper still gleaming.
