Although I did get some good weed from the grass hopper in the dam (some -extremely- potent/frosty white widow), I think the best coffeeshop in the dam has gotta be either the grey area of the dampkring. Best bud I smoked in amsterdam was definately the grey area buds. All my buddies (including this random guy we met in Berlin that ended up travelling with us) bought a gram of different bud/hash and we sat down with the house bong (a nice 3 footer) and sampled them all

I like how you can smoke in the restaurant area of the grasshopper.
