The Burger Boss only had a short reign in Chicago, as management has shuttered the Southport location.
The fast-casual restaurant opened in October 2013 sporting an identical menu to the original Elmwood Park restaurant, which is about to turn four years-old. A Facebook post confirmed the closing.
There were plans to expand the Burger Boss' empire with a third restaurant. It's unclear if a new location remains on management's radar, but Eater has reached out for more information.
