Others are more indigneous to my hometown in Saint Louis:
-A Saint Paul sandwich.
Can't say that
Punky or I have ever heard of that... is it from a particular restaurant or neighborhood?
St. Paul sandwiches are indigenous to Chop Suey restaurants in St. Louis. Basically a fried omelete sandwich with onions, green peppers, your choice of meat, served on sandwich bread. Different places will include pickles, mayo, and/or tomatoes. Can't seem to find them outside of Saint Louis.
Grew up on them... hope I never see one again
Like with anything, it depends on how its done. I've had pork steaks (usually from the barbecue grill) good enough to make you turn and slap your neighbor.
Well every town is going to have shorthand references to various locales and not too many people outside of this area are going to know where The Hill or The Landing or The Loop are...
Which is what makes them obscure references if not many people outside your circle knows about them. Sometimes you might say something that's very commonplace where you are, but totally unheard of anywhere else. I made a reference of going to Jefferson Barracks one time and the person I was talking to said "Who's he?"
hell, I didn't even find out where exactly "Dogtown" was until a couple years ago

I have found that fewer & fewer people know what or where the "innerbelt" is as the years go by, even though I-170 is just as busy as it ever was.
-Imo's (local pizza chain that specializes in St. Louis-style pizza).
I haven't found any middle ground on the Imo's issue; people either love it or hate it (personally I think it's vile).
I prefer Cecil Whittaker's (another St. Louis-only reference) myself, but Imo's is the chain that dominates St. Louis perhaps more than Domino's, Pizza Hut, or Papa John's and lays claim to being the original St. Louis-style pizza. Whatever.
-Vess soda (frequently outsells Pepsi and Coke in grocery stores).
There isn't enough Vess in this town to wash the taste of an Imo's pizza out of your mouth!
And of course Vess cream soda is red rather than gold like with most brands.
Two foods that I didn't know were St. Louis specific until I joined the Air Force are gooey butter cake and toasted ravioli... which lead to some long, long stretches of cravings in between trips home.
I didn't know that Chop Suey from Saint Louis was different than that elsewhere in the U.S. When I had takeout from other cities, it just didn't match up with the stuff from back home and it got to the point where eventually I
stopped having Chop Suey from outside Saint Louis.
