Have you been to Amsterdam before?
Other recommendations, places to go for eats, drinks etc
Obviously Amsterdam is famous for offering a particular pastime but that has changed a little since i was last there. Best to do your own research on that subject.
If you like good beer then hunt out any of the many 'Brown Cafés' traditional bars for delicious brews, good rustic food & convivial atmosphere.
For a pure Beer experience i'd recommendhttp://www.indewildeman.nl/index.php?lang=en&page=0
