Since this thread has devolved into a Texas versus the rest of the world...as most do...or which place has the best BBQ...as the rest of the threads where Texas is mentioned do...Let me just say this. I have eaten BBQ all over.
I like the Countly Line at the Lakes there in Austin; I also like this little hole in the wall a customer took me to in Fort Worth; I have eaten at Corky's and Rendevous in Memphis; I have eaten at little hole in the wall joints all over the South from Texas to the Carolinas....my only advice is to stay away from anything named Sonny's and most commercial joints as well. Also look for the places the locals eat at and try not to be a BBQ tourist that takes the fun out of eating the local flavors and enjoying them for what they are...different!
Personally I like Full Moon BBQ here in Birmingham because you can get all sorts of BBQ from beef to pork to chicken and it is all really good. I also love this little place down in Selma that only serves chopped pork sandwiches on three slices of white bread...The place has no name but the line is about a block long at 6am with guys getting their sandwiches for lunch that day and the old black man who ran it has passed it on to his son...and they only take CASH!
