Any insight from Sloopers/readers on what goes inside this (above pic) building and the one immediately to the south of it. When this picture was taken, no addresses were posted on the buildings, but last time I drove past, I believe some had been posted. These buildings would be the two immediately south of 1600 S. Prairie condos.
The building to the south of the one in the picture has "PECO" lettering on the front. Google searches turned up a cleaning/uniform services for restaurants, but both numbers were out of service or disconnected. Only a few times while out walking the dog have I seen any of the doors open or lights on and it looked like the building to the south of the one in the picture had a bunch of cars (possibly luxury) and boats inside. Money-laundering operation, much?
Can Sloopin's readers help me solve this mystery?
UPDATE and Photo from a reader:
I've attached a closeup photo of the building facade on Prairie that you posted about today. The images shows an electric train etched into the building:
