I thought I’d post a contraian view to WJ’s avid regionalism, and see when (or if) you all think something ceases being uniquely regional, and becomes something you can get everywhere.
Cesear Salad? Cobb Salad? Cheesesteaks? Tacos? Hamburgers? Mexican Food? BBQ? Roast beef Sandwiches? Fish Tacos? Sushi? Thai Food? Hot Dogs? Fried Chicken and Steak?
Are these forever frozen in the regional culture that spawned them, or do some(all?) dishes find there way into the american food idiom? Weren’t most foods regional to start with?
