East Square Plaza basement mensroom

For a couple weeks have come across understall action in the mensroom in the basement of the East Square Plaza building where the Underground Art gallery used to be. I believe the floor is empty so it is fairly safe and the bathroom is roomy with multiple stalls. The mensroom is tucked behind a little kitchen area in the west hallway of the basement. Seems to be best around noon on weekdays, although later evening seems to be good too.
