For example, every non-vegetarian former resident of Springfield, MO I've ever talked to swears that Springfield-style Cashew Chicken is far and away superior to Cashew Chicken anywhere else. Also, in the Midwest (or at least my part), Crab Ragoon's been a popular appetizer since at least the early eighties, but I remember trying to order it in Florida in 1999. I got pretty much same WTF looks you'd get trying to order it in China.
Anyway, I'm trying to come up with regional dishes a character who's traveled extensively through the US might have encountered. So far all I've got is a short bullet list off of Wikipedia. Also, does anyone know of any notable differences between DC and LA. I've tried googling menus, but it doesn't really indicate if the dishes are prepared differently.
Also, I understand that you can get crab Ragoon in Tampa, FL. How recent is that, or was I just in the wrong part of the state?
