After problems with "lightweight" deals from certain coffeeshops in town, this morning I went back to the old favourite Eastwood and of course it was no shock that the great "superskunk" I bought (€12.00 for 2.5g) weighs in bang on the button.
It may not be one of the nicest looking coffeeshops and the menu not the biggest, but i'm always given a happy greeting and the skunk always has the desired effect.
If you're a hash fan, Eastwood has a local reputation for selling some pretty decent brown stuff too @ around €6.00 for a g.
Get on bus 22 or 43 - jump out at the windmill (stop in for a beer if they're open) and Eastwood is just one minute away.
Do yourself a favour - explore Amsterdam properly, not just the centrum...
