The "Wallen" is the red light district. Can be done in half an hour as it's been cleaned up and is now managed properly by the government. Only a few streets remain, more of a token thing than the place it once was.
Don't waste your time with the Heineken Experience or De Beers Diamond tour, they've just little tours trying to get you to buy stuff, in fact last time I went was with my wife who'd never been to Holland before and I was seriously ****** off with how much they ruined it. The sex museum is crap too, it's just a few rooms full of sex toys and stirrups and whatnot.
The pleins are usually decent on weekends, Museumplein in particular usually has a nice buzz to it and there are loads of bars and restaurants around. The same goes for the Dam, Waterlooplein, Rembrandplein, and more. Actually,
this might come in handy.
If you're taking the ladyfriend and she enjoys seeing special shops, then the
Bijenkorf is a must. Think of it as Holland's Harrods. Not quite as glammy and glitzy but worth a wander through.
If you're looking to do a canal tour, then use Rederij Plas, they are the best and also quite affordable, and often they'll dish out random restaurant vouchers and stuff on the boat so you might get lucky.
If you want a proper whole day tour, then go to the tour stand on the main walk from Amsterdam Centraal, it's about 200m on the right and ask for a Zaanse Schans tour. It's great, they'll take you through a bit of the countryside and show you some windmills with a bit of history, you'll see how "klompen" (clogs) are made, as well as cheese and usually a tulip farm (season dependent). Really nice day out which shows you some of Holland's culture, which isn't blow and brass.
If you want a puff, then go to
Abraxas. Lovely little place which we went to when I lived there and you get to keep the ash trays as souvenirs (not sure if they still do this, but they did when I used to go there). It's away from the robbing touristy places and has a nice atmosphere.
For junk food, you
must try Febo. Preferrably after a puff. Amazing food for £pittance.
Have fun
