Well worth the trip, we stopped in Resin 1st when I last visited 'Dam in February, it was about 1030am, and the budtender suggested it was definitely a place to visit prior to checking in the hotel - Boerejongens has the best menu in town in his opinion. Usually they have around 20 weed strains on the menu at opening time (& several hashes), some of which sell out very quickly (White Choco, Sanguna, S5 Juice for instance). Better value than Dampkring with arguably a lot more interesting strains that appear from time to time on the menu. They also gave me an 9E discount on an 89 Euro order, 2 packs of Futurolas & despite the queue behind me, the budtenders were totally happy to let me & the mrs examine quite a few strains before buying.
On the downside, no smoking inside, though you can roll & there are benches outside. I recommend you pay a visit (try to get there before noon) if venturing West, it hardly takes long on the tram (Postjesweg/De Withestraat stop) from anywhere in the city, anyone who thinks it does doesn't know the true meaning of daily commuting!
I can also vouch for De Graal - Epsilon knows what he's talking about - my favourite cs to hang out, in De Pijp, my favourite part of the city.
