A local place that I think would hit it big just about anywhere (other than Louisiana for obv reasons) is a "fast" food cajun place. We have 2 in our college area and both do really well. I can't believe more haven't popped up in other places. It is a pretty simple concept. They have a rotating menu that they make daily and have listed on a chalkboard. They keep everything cooking slow in large pots and serve the sauce up over your choice of penne pasta or white rice and a piece of bread. It is <$10 meal and usually the best spot to go for a quick lunch/dinner.
