In today's day and age, it seems like you can find just about any type of food you want, especially if you live in a big city. Want a super-authentic banh mi, or perhaps a traditional Belgian Liège waffle? There's a food truck for that. Heck, even if you live in the middle of nowhere you can log on to sites like Goldbely and order food items right off the menu from some of the country's most legendary restaurants. But from a stuffed sandwich in Lincoln, Neb. to a breakfast sausage that's available only near Cincinnati, there are still plenty of regional specialties that are certainly worth traveling for.

When you think about it, all food started out as a regional specialty. Even pizza, one of the most popular foods in America, got its start as a regional style of flatbread in Naples before spreading like wildfire after immigrants introduced it to the American palate. For various reasons, some foods catch on in popularity and become household names, and others linger in relative obscurity, beloved to a handful of lucky locals while the rest of the country is barely aware of its existence.
