I have visited this area a couple times now, so I wanted to share now that I know it wasn't a one-hit wonder. On Rayford Rd. just past the railroad tracks heading east, there is a cluster of food trucks on a vacant lot. There is a cupcake truck, a Cajun food truck, snocone stand, etc.
The cupcakes are pretty good! Lots to choose from. The Cajun food truck is amazing. I have had the jambalaya and today, the shrimp and grits. Probably as good or better than any "Cajun" restaurant in the area. If you have some time, I would really recommend making a run by this place.
