Wow - the guy that started Blues Hog BBQ passed in the last few weeks too. Tough times for the BBQ community. Agree with the original post, Q39 has incredible food, hopefully that doesn't change. Q39 is far better than Jack's Stack (I've been there twice in the past 6 months, WP Plaza location, and it was meh both times. I'm trying to Joe's KC BBQ but it might be a month or two before I can get there.
I would rate Q39 as a tie with Joe's of Kansas City for the best we tried. Joe's makes more sense to me as a lunch place while Q39 with wait staff might be a better choice for dinner.
