I hate to advocate drugs, alcohol, violence, or insanity to anyone, but they've always worked for me.
My Brother's Place
This place is open from 7am to 2am everyday, although you could never tell. During lunch hour it attracts some local heroin addicts and construction workers looking to score smack and strong drinks. Otherwise, it is a good place to find sleazy hookers, a communicable disease or the occasional toothless barfly. A great bar if you like to live on the outskirts of normal, functioning society...which you obviously do or you wouldn't even know about this site.
Update: My Brother's Place has been closed for some years now.
