Burger King moved out in 2009, and mall management placed a wall over the 2,400 square foot restaurant while it waited to find a replacement tenant, Tom Dahlke, the mall's general manager, told Verify. Dahlke said that though management and some mall staff knew the restaurant was still there, it had gone viral after a vendor in the mall passed by while the door was open and took a picture.
