Bandanas is a national chain. Its alright, but not in the top 10 best places in KC. Its about on par with something like Rib Crib or Famous Daves.
Its completely acceptable BBQ. If you were eating BBQ in say, Vermont, it might be the best place around for miles. In KC, or Memphis, or Austin, etc, it doesn't quite stack up.
alternately, if you are ever driving through KC on I-70, some of the better places that are REAL close to the highway are Zarda BBQ in Blue springs, only about 1 mile south of the Highway 7 exit on I70, and theres a Gates on 40 Hwy in Independence, only about 1 mile NorthWest of the 40Hwy exit off I-70(first exit past Noland Rd if you are headed Westbound on I70)
