Freddys not dead
Huntsville Tx is awesome
My all time favorite is the Whately Diner (after the town with the same name in Western Massachusetts).
Now if you are looking to explore the farthest reaches of your constitution; try the woo pig at Uncle Henry's in Sheridan Arkansas. I just tried one of the best Cuban sandwiches at a place called Havana Cafe in Eugene Oregon. Both are pork with more pork however!
