Today was a nice day.

Today was a nice day. Now, I am feeling unaccountably pissy. (Not really unaccountably, but whatever.) Therefore, a purposeless rebuttal to a comment or post made within recent memory. The appetizer originating in St. Louis is called toasted ravioli and it is, in fact, fried, in its original and truest form. Later low fat weirdness came up with baked recipes, but that is not the real deal. Stupid and pointless, I know, but I'm in that mood. (Pete will back me up, and, as we all know, that is the definitive research source.)
Other uniquely St. Louis foods include gooey butter cake, and provel cheese (integral to the horrifying thing known as St. Louis style pizza). Not entirely unique, but strongly associated with the city is the fried brain sandwich (usually calf). Ted Drewes is a St. Louis frozen custard purveyor credited with inventing the Concrete, later borrowed by DQ as their Blizzard. Except you really can turn a Concrete upside down and it doesn't move. Personally, I liked Fritz's custard better than Ted Drewes'. 7-Up was also invented in St. Louis, and originally contained lithium (making it far more likely to keep you mellow than Mello Yellow, which is highly caffeinated).
Pop food culture aside, St. Louis absolutely has some of the best Italian food you will have anywhere in the US, including some amazing bakery and pastry shops. If you go there, you should save your pennies and eat on The Hill. It's worth it.
