The key to it all is a place called "Sizzle Pie". They're big on social media, big on 'Pizza Culture Art' and they have multiple locations across different states.
I checked their downtown east side Portland location, and I think it's a front for a temple.
The pizza store has easy access to a building next door, but listed as being on a different street. This building is a featureless white building with no windows, one garage door, one front door with a metal grill, and multiple security cameras.
If you walked out of the back door of Sizzle Pie, you could walk through a walled off and secluded back area before accessing the "temple".
Sizzle Pie location: 624 E Burnside St, Portland, Oregon
