Petulia - Companions of the Evergreen Lodge
Archie dutifully tries to return the stolen tuba to the address given him by Petulia - "... the Companions of the Evergreen Lodge on Grant Street". He finds the place but can't get a response at the front door.
Then ... Assuming she meant Grant Avenue, she was close - this location is at 782 Sacramento Street, near the corner with Grant Avenue.
... and Now, the view east down Sacramento from Grant today. The 782 entrance door is now gated. As is the case with many parts of Chinatown there has been little change over the last half century, one of the reasons the neighborhood continues to hold onto its character. May it stay that way.
