Playboy magazine once named Madam's Organ one of its favorite bars in America. The ramshackle place has been around forever, and its nightly blues, rock and bluegrass shows can be downright riot-inducing. There's a raunchy bar-dancing scene and funky decor with stuffed animals and bizarre paintings on the 1st floor. The rooftop deck is more mellow. The big-boobed mural outside is a classic.
