The Burger Shack's STUFFED burgers are unique in that all the delicious ingredients are stuffed in the beef.  Our 94% lean beef is naturally raised on open-range pastures, without any needless antibiotics or additives. Feeling hungry for some comfort food?  We also have 100% all-beef hot dogs, fresh-grilled chicken sandwiches, wraps, pulled pork and turkey, and salads.  We're located near the Lehigh Valley Mall without all the traffic, minutes from Allentown, Bethlehem, Easton, and 3 minutes off Route 22, Fullerton exit.
