This is likely the best BBQ to be found in the Phoenix metro. It's far and away better than anything to be had in southern California and comparable to the mid-range places in more BBQ-centric parts of the U.S. In Phoenix, that puts it at 4 stars and I'd give it 5 if I didn't have such a great experience at another BBQ joint a month before in another state.
Bottom line: if you desperately need a BBQ fix, you could do a lot worse in Phoenix and if you are a little less desperate and just looking for some good BBQ, you will still leave satisfied.
