Getting back to ya'll re The Patch. Here's a recent, interesting article about a guy from The Patch in New City.

I know folks who live there and call the neighborhood "The Patch." It shows up on real estate sites also. Frankly, there isn't much need to call it that from an informational standpoint, since the area is dominated by Smith Park.
A little noodling showed that at least four different neighborhoods (in addition to the Logan Squarish one) can be or were once "The Patch": (1) Smith Park, (2) the area further east on Grand near Ogden and best known here, possibly, as Little Sicily (Provincia D'Amato-Bari), (3) Bridgeport (from "The Cabbage Patch" -- compare the similar 'hood in Toronto), and (4) (archaic) the River North area where the Chicago River splits.
A common theme among "patch" neighborhoods in Chicago appears to be that they are or were insular, white-ethnic, blue-collar places where police and city workers live/lived.
Metroblogging Chicago has some wack information about The Patch, Little Sicily and Chicago neighborhoods in general as part of a bit about Dennis Farina's character on Law & Order.
I live in a no-man's land myself, the lost trapezoid of "Lakeview" that is defined by Ashland, Lincoln, Addison, and Irving. Not quite North Center, Roscoe Village, Lincoln Square, etc, etc. On the most informed maps, it's us. Lakeview. Lots of stuff is close, but very little good is around the corner (Diner Grill and Ginger's excepted).
In addition to the good PR and Mexican in Terrence's area, I guess I'd add Polish. That's more diversity than what I've got. Not Uptown, Albany Park, or Rodger's Park, but not Iowa, either.
