I visited this place in May 2012, after sightseeing most of the day in Haarlem. I'm writing this review several months late only because I couldn't remember the name of it, but with the help of FBN recently, I located it on the map and found the name. On the day we visited, my friend and I were looking for the closest CS to the Grote Markt, and we stumbled upon this gem, not knowing anything about it beforehand. We got a gram of Cheese, then each had a coffee. Because we purchased the weed, which was 11E, the budtender kindly didn't charge us for the hot beverages. The smoke was sensational, felt pretty high. It was late afternoon, and first smoke of the day, so that may have helped, too. When we got there, the shop was empty, but then it started to fill up with locals, mostly guys between the ages of 20-30. They were all psyched up about the upcoming Euro 2012 tournament which was just days away from starting. The Orange Crush didn't fare too well in the tournament, but fortunately, I didn't see these guys in the aftermath of that
I'm not sure how this shop compares now with the way it was run by the previous owners, but there was room in there for 10-15 people, because that's how many were there when we left. It didn't seem too crowded.
If you haven't been to Haarlem, go. You won't regret it. It's beautiful, charming and as others have noted extensively on this website, the weed isn't bad either. And it's close to Amsterdam. Just get on the train and go!
