Most of the East of the Mississippi I can agree with and I've tried most of them. The Brunswick stew and Burgoo I've never heard of. I might have to try them although I hate Lima beans and haven't had them since I was a kid. They always tasted dry and powdery on the inside, but my parents were bad cooks and made me unreasonably hate a lot of guys I've had to reduced as an adult.

The map would probably be better if most states had room for 2 or 3 things as many states are big enough to have distrinct regions of their own. For the Mid-Atlantic, we're missing shoofly pie, beef on weck, NYC Pizza, Primanti Bros sandwich, and a ton of other Amish foods and more.
