... the Bank of Montreal/Hockey Hall of Fame building on the northwest corner of Front and Yonge Streets.  The door that isn't the entrance to the Hockey Hall of Fame.  Climb up the steps, stand on tippy toe and squint through the grimy glass at the stained glass dome over, what I'm guessing, was the main banking hall -
