Yep, the Anne Frank house is worth a visit. There's also the Rijksmuseum, the Stedelijk, and loads of old churches and other museums. Plus there's the tours and canal cruises. There's even a sex museum if you want to combine porn with culture. Unlike Tina and the like, we're not all obsessed with sex (only because she isn't getting any!)
Fair enough, im not going to lie i generally go over there for some smoking and walking round the red light district thats the main attraction for me as i go with my mates. If i went with the family/mrs then im sure i would be a bit more interested in their museums etc
