I've often thought that if someone wanted to make a lot of money they could bring a product that is really popular in their area to a new area. From the land that brought you chicken wings (we don't call them buffalo wings since that's where we are) there is another extremely popular item called roast beef on kimmelwick or simply beef on weck. It's topped with a little horse radish hot enough to clear out your sinus. I have never seen the sandwich available anywhere else. Easy enough to make anywhere in the world as long as you can get the kimmelwick rolls.
