Buddy of mine is traveling through Columbia on his way to Daytona and looking for a lunch suggestion. I haven't been plugged in to the dining scene for the past 10 years, so I need some help. Looking for unique spots, doesn't need to be fancy. Hole in the wall is fine as long as the food is good. Past hits have been Rockaway and Yesterday's. Bonus points if you can suggest a specific "signature" dish.
