Vertigo - Ernie's Restaurant
Elster tells Scottie he will be dining at Ernie's with his wife and suggests he hang out there to see what she looks like. The famous Ernie's, a landmark for 54 years until it closed in 1996, was at 847 Montgomery Street in San Francisco (map) but these scenes were actually filmed at Paramount Studios in Hollywood where Hitchcock painstakingly replicated the restaurant.
Then ... Scottie, at the bar at far right, sneaks a peek at Madeleine, way over to the left.
... in 1961 ... this vintage photo pictures customers relaxing in Ernie's Ambrosia room. Note the same wallpaper as in the studio recreation above. Note also the wooden wainscot wrapped around the wall in both images.
Then ... the exterior of Ernie's, seen here as Scottie waits outside, was also recreated in the studio just for this scene. That's a lot of work for a shot that lasts only for a few seconds but such was Hitchcock's famous attention to detail.
... and Now, the building is still there but now houses offices and shops.
By the time Madeleine leaves the restaurant, poor Scottie is a goner.
