Hum, there is more than one ... Only in Amsterdam there are at least 2 (went there 2 days ago), one in Central Station and one not far from the Science Museum (that I could see from the train leaving the Central Station :D ). And no doubt there are more in the inner city.

Then there is also at least one in Utrecht Central, so we are down to 3 already.

Anyway, I know it was not your point.

Besides, as a Frenchman (living in the Netherlands), I'm not fond at all of Dutch coffee, but hey, it could probably work in "New Amsterdam" ;)
