In my previous post regarding Frederic Odun Arechaga, his store El Sabarum and organazation the Sabaean Order of Amn, I wondered whether the Tonic Room knows what used to take place in their building.
Thanks to an anonymous response, I know the answer. Yes, they know very well. Not only do they know, but they've found artifacts of the Sabaeans who once occupied the space. They also have a nice concise history posted.
Thank you, anonymous poster!
