First rule of robot club...
Robot Club bills itself as "a robot-themed restaurant open for lunch and dinner" as well as "the world's first permanent robot fighting facility open to the public seven days a week." Apparently they're being picketed by
PETR: People for the Ethical Treatment of Robots. (There has to be a pun in there somewhere for this usage of "picketed"...) Found from a recent
pgh.pm posting.
