Try a search it has been covered not long ago.
I went last month for a weekend.
I was so impressed with there transport system amongst other things

Great place but i couldnt stay there for longer than a weekend. A lot of places didnt allow smoking of tobacco in the bars but green is allowed! this made a mess of me as i dont really smoke it that often! ha
try this place, its one of the best places for it: cafe 420 amsterdam. the 420 haze

anyway there is the usual by day, heineken factory, sex museum etc, if the weather is good, get the train to vandervoort and get on the beach and check the beach clubs out!
By night the red light, always a laugh if your with the lads! watch out for the alley of temptation if you have a mrs!!
