I hate to advocate drugs, alcohol, violence, or insanity to anyone, but they've always worked for me.
In the center of Amsterdam you'll find The Minds which is easily associated with the punk/squat scene.
The best thing about the Minds (apart from the athmosphere) is it's closing time, although it always depends on the owner's ("Dre") mood. Be sure to be in on time because after official closing time the blinds close and you won't make a chance.
They serve dutch beer named Budels which is best consumed from the bottle -not for the taste but it looks cooler and they serve draft in those small shitty glasses.
The Minds is famous for their live bands at Queens Day (30th april).
The Green Bar has been open twenty four hours a day, every day since 1968 and has never closed. The bartender is enclosed in a huge iron cage. To obtain a drink, one hands 18 KSh through the grill and receives one warm, 500ml bottle of Tusker Beer. (If you want a cold one ask for a 'Tusker baridi'). Read more »
An old fishermans pub which looks over the local harbour. Good music and late drinking.
Many visitors and locals alike, but more men than women overall and some class sleazy lines to be heard. Good laugh.
I need to travel again... explaining the concept of 'sleazy bars' evokes too many interesting places from the dark corners of my friends' memories. And of the cities they come from.
Airport, Am Dobben 70, Bremen. Opens at 11 at night. Beware, they already close around 5 am during the week, but in the weekends you can be surprised by how light it actually is when you get out, even in the winter. And the fresh air...!
Other places in Bremen on their way, once the memory of my friend is restored sufficiently to allow others to actually try and find the place. ("It's somewhere on a crossroads.")
