I really like Bobby-Q, but it's nothing amazing. For me it's more restaurant than BBQ-joint. I really like the ribs, even though they are fall off the bone soft. Brisket wasn't anything special. It's all very edible, if not mind-blowing. Usually just makes me want to go home and fire up my smoker.
It's probably my favorite BBQ place in Phoenix that isn't a pain in the ass for me to get to. (Little Miss BBQ in Tempe is pretty dang good, but they're only open for lunch).
I have no idea what they are talking about with the "Best in the US" stuff though.
