This beloved Adams-Morgan hangout fulfills owner Bill Duggan's definition of a good bar: great sounds and sweaty people. The great sounds feature One Night Stand, a jazz group, on Monday; bluesman Ben Andrews on Tuesday; bluegrass with Bob Perilla & the Big Hillbilly Bluegrass Band on Wednesday; and the salsa sounds of Patrick Alban and Noche Latina on Thursday, which is also Ladies' Night. On Friday and Saturday nights, regional blues groups pack the place. The club includes a wide-open bar decorated eclectically with a 150-year-old gilded mirror, stuffed fish and animal heads, and paintings of nudes. The second-floor bar is called Big Daddy's Love Lounge & Pick-Up Joint, which tells you everything you need to know. Other points to note: You can play darts, and redheads pay half-price for drinks. For what it's worth, Playboy's May 2000 issue named Madam's Organ one of the 25 best bars in America. Food is served, but I'd eat elsewhere.
