PROS: We discovered J&J BBQ in 2006, by accident. In our opinion, J&J's food is an excellent value and just as good as the more expensive Rudy's BBQ and better than Pokey Joe's. We very much recommend J&J's and plan to get J&J to cater a family gathering for us this summer.
CONS: We usually get take-out because the only time we ate inside (Sunday lunch) and sat at a table in the center of the restaurant, acoustics were so bad that I could hardly hear my friend sitting right beside me. (And there was no band/music playing at the time.) Maybe we were just sitting in a bad spot but the experience has so far prevented us from dining in.
I would be interested to know if others have experienced the same.
