Been meaning to get to Zac's since it was first mentioned in the discussion group.  Zac's burgers are cooked on the grill, flattened with a spatula to spread them out.  Philly cheesesteak attitude when it comes to ordering.  See the rules on the right.  Great milk shakes too, made from ice cream and milk the old fashioned way.

There are two other Zacs - Providence Road in Secane PA and Concord Road in Aston PA.
