I couldn't find a general topic on this (other than with a time restriction). Eater is having a barbecue week, which includes a "thumbnail" history by Sietsema (which skips from Pearson's to Hill Country, ignoring Dinosaur, Rub, Bonelick Park, Daisy May, etc) and an overview of the current scene--and its "cultural implications"--by English Nick.
Made me wonder which places people here currently rate. My most recent experiences have been at Hill Country out of sheer convenience. I had deep reservations about Mighty Quinn, based on several visits. It's a while since my trips to Arrogant Swine. Oh, and John Brown Smokehouse was terrible.
