Small nice bar with a good feel and sells pale ale!
Cafe L'affiche
Cute hidden away corner bar full of locals, not touristy. It is here.
Roest
Sweet hang out a bit out of town but really good for outdoor drinking action. It's best to bike to this as taxis are pricey in AMS, although if you are not local it might be hard to find.
Weber
Good on a Thursday night, it gets busy later on and has some hot locals. It's quite small so it's easy to meet people and have a chat with some randoms.
Club NYX
This opens late even in the week and although is officially a gay bar it gets quite a mixed crowd and has a few floors with different music on. And the toilet sink is a giant penis.
The street NYX (pronounced nicks) is on also has some good bars to hang out in. The street is quite busy at night and has some nice restaurants too.
De Pijp
There are loads of bars down this street and if you just wander around you will find a few busy ones.
Noordermarkt
This has a couple of nice bars which you can sit outside of in Summer and are nice hang outs anyway.
Cafe Finch is nice and Proust.
Jordaan
There is a nice bar called Harlem. It sells soul food. It's on Haarlemmerstraat. This street is generally really great and you could spend all night there.
Tuinstraat is a street in the Jordaan with loads of bars and restaurants on it so always pretty busy and not touristy.
Clubs
Chicago Social Club - this club is on Leidseplein so is easy to get to and usually plays ok music.
De School - the new Trou but is not located in the West also.
