From Episode #85, The Case of the Wary Wildcatter
The Monterey Building
Here are some pictures of the Monterey building as seen in the episode and some recent pictures provided by Eric Cooper. The building is now located at 804 N. Las Palmas Avenue, just a couple blocks south of the studios where the series was filmed at the time. The address of the Monterey was at 800 N. Las Palmas Avenue as can be seen by the number on the door.
