Although I've lived in the Netherlands for many years, when I'm in Den Haag I invariably visit the Passage - so elegant and atmospheric - especially around Christmas with the massive, and well decorated tree in the middle. Shops are high quality and tend to be specialised. Akermaan's is definitely the place to for quality pens and writing supplies for example. Excellent Apple shop well but also many others e.g. Dok for kitchen equipment. There are are also some excellent places to have a tea / or coffee & have lunch - but don't miss those on Kettingstraat as well. Hint - if its raining of course you can just stay in the Passage but if you want to cut through to Kettingstraat go via Dok - they have an a second door on Kettingstraat and you can browse there too!
