Shaffer Farms is by far is the closest that we have found to Texas BBQ. It is located in Summertown, Tennessee. It is a custom meat shop, as well as a very small restaurant that serves awesome melt-in-your-mouth Brisket, BBQ Chicken, potato salad, three different types of beans, corn on the cob, sweet tea, and lemonade. It is out in the middle of nowhere, so I would suggest using google maps, but it is worth the drive. It is not very expensive and the portion size is large enough that you do not leave hungry.
