Boerenjongens coffeeshop in Vondelbuurt, one of the best coffeeshops in A'dam, hands down. Friendly people, great strains. Original Dampkring, in the Rembrandtplein, my favourite coffeshop, I more or less lived in here for the best part of 5 years. Grey Area gets a pick, but it's pricey, and they turn up when they want. 1e Hulp, also a nice place. De Pijp,and De Tweede Kamer, worth a look
If you've got balls of steel, try this, a swing from the top of a hotel, not for the faint hearted
