Blue Havana, a store that was part of The Alley series of stores, was recently torn down on Belmont near Clark. There was a brief period of time where you could see a tunnel or room in the basement that led underneath the alleyway there. It has since been covered up along with the rest of the basement. Does anyone know what that was? It may have been something interesting like a secret room during Prohibition or just a tunnel that led to Igor's Dungeon across the alley.
