My state (Or.) is known for hazel nuts and salmon. My city is known for food carts. All over town vacant lots and the sidewalk side of parking lots have been converted into food cart clusters. If you can think of a cuisine it's probably represented somewhere in town. Because they don't have extensive menus they specialize in a few things which I believe often increases quality. Off the top of my head I can think of Cuban, various South American, SE Asian, Mexican, Polish, Greek, African, BBQ, Southern, Korean/Mex fusion, Vegan, Lebanese, Fried Pie, Breakfast, Pizza, Czech, Indian, Japanese and many more that I've never tried or even seen, there must be a few hundred food carts around now a days. It's amazing. http://www.foodcartsportland.com/ has a small round up of some of the carts, but as I look over their site I see many gaps in their knowledge, it would be a full time job to keep on top of it.
