Benny's
Benny's is the restaurant the Goth Kids are seen at in the Season Seven episode, "Raisins". The name references the real restaurant named Denny’s.
It's possible the restaurant was bought out by Village Inn as the interior is exactly the same with the same waitress who often argues with the Goth Kids still working there although the background doesn't match but this may just be a continuity error.
Background
The Goth kids sit at Benny's all night drinking coffee, believing they are non-conformists. When the waitress becomes annoyed and tells them they should "get a life", the Goth Kids ridicule her for being a conformist.
In "Raisins" Stan Marsh briefly joins the Goth Kids when Wendy Testaburger leaves him for Tolkien Black. Kyle Broflovski visits Stan at Benny's, in an attempt to persuade him to return to his regular life. Much to his dismay, the Goth Kids reject the plea and accuse Kyle of living in a conformist Disney fairy-tale.
In "The Ungroundable" the Goth Kids are seen sitting at Benny's again drinking coffee while wondering how sending away the vampires' leader did not stop the others. They are mistaken as Vamp Kids by the waitress, who says that for her they "all look the same". Then Butters Stotch appears and tells the Goth Kids that destroying the vampires' hideout would turn them human again, eventually leading the Goth Kids to the 'Hot Topic' store.
