To quote Southwest Diner co-owner Jonathan Jones: “A diner in St. Louis has to have a slinger.” It may not be as controversial, but the slinger has earned its place alongside Provel-topped pizza and bread-sliced bagels as one of St. Louis’ most debated dishes.
A classic slinger usually comprises eggs, meat, potato, chili and cheese. However, once you get into the hard-and-fast details, nothing is certain. As far as toppings go, the chili versus gravy argument has long separated the dish’s most passionate supporters.
While torrents of chili dress the slingers at most local diners, Jones defends Southwest’s use of gravy with a simple question: “Um, have you had our gravy?”
