I have several that I'm partial to ... Chisholm Trail in Lockhart, Tx., City Barbecue in Columbus, Oh., BoneDaddy's in Midland, Mi., Pappy's in St. Louis, Mo., Sweet Baby Ray's in Wood Dale, Il., 17th St in Marion & O'Fallon, Il.
Best of these is either Pappy's in St. Louis or Bonedaddy's in Midland, Mi.
I'm a long time fan of Skip Steele, pitmaster at Pappy's or maybe by now ex-pitmaster. Skip has his own place not to far from Pappy's - Bogart's (I haven't been to Bogart's yet) - and Skip was doing double duty - being pitmaster at both the last I knew. Or Bonedaddy's in Midland, Mi. owned by legendery ribber Billy "Bones" Wall's son Bill. Bill is also the pitmaster. BoneDaddy's competes at the Best of The West, in Reno, over the Labor Day weekend and consistently either comes home with the Championship trophy or People's Choice award.
My local favorite is Uncle Bub's in Westmont, Il. Mark Linc is the owner and pitmaster. Uncle Bub's is a restaraunt, caterer, and competition barbecue team - I don't compete but got to hang out with them a couple years ago at Westmont's Red, White, and Barbecue over Memorial Day weekend. I'm partial to Uncle Bub's rib tips and burnt ends. My wife likes their chicken. Mark and his team went to Best of The West for the first time in 2011 and came home with the Best Sauce trophy. Uncle Bub's also bottles their barbecue sauce and it is available either at the restaraunt or on their web site - www.unclebubs.com .
