5. There Used to be a Confectionery Store (and Subway) Inside the Sea View Hospital Complex

There was once a confectionery store selling things like cigars, stationery, Coca Cola and more. Like much of the above ground tunnels, the space is currently used for storage but the old school signage still remains. In 2011, a Subway (the deli chain) opened inside the Robitzek Building but it has since closed.
