I don't know how you are heading north from Shreveport, but If you take Highway 3 better known as Benton Road from Shreveport, (well, actually Bossier city) north to Hope,Arkansas, where you will meet up with I-30, you pass through Lewisville, AR. There's a little bitty restaurant called Burge's famous for their smoked turkeys. http://www.smokedturkeys.com Honestly, I've never eaten there and it's been a long time since I've made the drive in that direction. Have you checked out Southern Living's website? I don't know if they list restuarants, but they usually do one page features on small towns around the south (including Texas and Oklahoma). That information may be accessible on their website, but you may have to register.
