South Minneapolis is more hoity-toity by the year. Fancy restaurants like Heyday and Scena are fine additions for foodies, but their arrival also signals a transition to a more refined, less gritty past. In the face of this perfumed wave, the CC Club bar is one holdout. Bob's is another. Since the mid-'90s, the joint takes all kinds from the neighborhood: On any given morning, its clients are old couples, punks, or hipsters. Of course, what makes Bob's unique is its special appeal to bikers, who line up their choppers out front, grab benches out there, and down cup after cup as they chat about life on two wheels. Some favor the Japanese-made "crotch rocket" speed machines, while others like riding a huge hog; leather's a must. Inside, buy a can of Bob's to take home, and the instructions will tell you it's best enjoyed with a cigarette, just like most of the bikers take it. It's subversive. Gritty. Don't go changing all the way just yet, South Side.
