Inspired by AVI's map of Massachusetts stereotypes, I looked for a similar map of Georgia. There isn't one, probably because the kind of clever Buzzfeed-types who make such maps don't know anything about Georgia. Outside of Atlanta and perhaps Savannah, the whole thing would be marked, "Here be Dragons."
But I did find a map of the closer-in parts of metro Atlanta that fits the bill.
I went to High School in "Prime Real Estate." The part they call "The Mexico," which is properly known as Chamblee, I've always heard called "Chambodia." It has at least as many Asian immigrants as Mexican ones, and it's an excellent source for authentic cuisine from anywhere. If you hit the area, try Los Americas or El Taco Veloz.
