Thanks to a recent post at the blog 8Asians.com, I have discovered the Venn Food Diagrams series of posts at LA Weekly's food blog Squid Ink. It features what LA folk think certain groups of people eat vs what those people actually eat.
I find it absolutely fascinating, with plenty of thoughts that could go off in different directions. If nothing else, it might provide you with a list of some foods you should consider eating or making. It is kind of funny to see that Angelenos think that Japanese eat a lot of dolphin and whale, that Koreans like (Korean) tacos, and that the American Midwest is the land of cheese steaks and Buffalo wings.
