I was just alerted to this fantastic article recently run in Poor Taste magazine by sometimes WWEIL contributor and generally excellent dude, Erik Pepple. "The 100 Hundred Greatest Cult Restaurants in America" is an epic list--and not so subtle challenge to the gastronomically inclined--that scours our great nation in search of those joints that elicit fervent devotion and violent salivation from their customers.
Personally I would've liked to have seen Cleveland Heights classic-cum-crunchy diner, Tommy's on the list, as well as Columbus' Jenni's Splendid Ice Creams
