I gotta say, I find Polly Esthers and the like absolutely intolerable [see the Adams Morgan thread, though P.E. and Tequila Beach appear to be extreme versions of what's happening in A.M.].
If I want a change of pace from any kind of indie-type scene, I'd rather head to Biddy Mulligan's, Whitlow's, Gazuza, Nanny O'Brien's or Stetson's Grill...
