Hannekes Boom is one of the nicest waterfront café in Amsterdam to have a beer when it's sunny. Close to Central Station, the place isn't crowded by tourists, but you need to be there early to get a seat.
Unfortunately it’s not in Amsterdam but De Pont, museum of contemporary art is worth the 1,5 hour trip with the train. The building itself is beautiful, it’s a former wool mill but also there collection is worth seeing!
Jenever is a traditional Dutch spirit, sometimes called Dutch gin or wodka in English. Wynand Fockink has a distillery and tasting house right at the very hart of Amsterdam. This place is frequented by locals and tourist alike because of their delicious jenever. Be sure to try a glass of Wynand Fockink Superior. If they empty the bottle while filling your glass you're entitled to a so-called 'Amsterdammertje'; you'll have to drink your glass in one gulp and then you get a free refill.
A few years ago, the Volkskrant (one of the countries biggest newspaper) moved office to a new location. Their old headquarter now houses hundreds of artists and musician; along with dance studios, a bar/club with panorama over the city, a dreadlock 'doctor', a Russian cultural centre, a cyberpunk gallery and my photo studio on the 4th floor. It was a conscious choice by the founders to create a total melting pot. In the basement for example, 3 doors away from our music studio, you will find some cheerful weed smoking hiphop producers from the Bijlmer (the 'ghetto' of Amsterdam); an ex-yougoslavian hardcore drummer with a full analogue recording studio and a ballet school run by an obese woman in her 70's. Ok, it might seem artificial, but it really is quite magical!
