Stay busy, get plenty of exercise, and don't drink too much. Then again, don't drink too little.
I remember my dad taking me there when I was little and he place is exactly the same. Bill's bar hasn't changed in almost 35 years. Two stinky bathrooms, no food, beer can sculptures behind the bar.
The patrons (and that being kind) are a mix of druggies, drunks and derilicts.
The place usally closes around 5 am and opens around 11am. There was one time when one of the drunks had his head down on the bar, they thought he was sleeping, when they went to wake him they found that he was dead! He had been there for a couple of hours and no one noticed. The beer on tap is cheap and cold, and the bartenders friendly. A great place for people watching.
