Most Amsterdamers would agree with me that Damrak, Kalverstraat and Nieuwendijk are low-quality, tacky tourist traps. There are a few nice shops in those streets, but there are so many better places to go in Amsterdam. Try Beethovenstraat, Haarlemmerdijk, De Negen Straatjes, Dappermarkt, or even the market in De Amsterdamse Poort (close to Bijlmer Arena Station).
