Once in Den Haag, go to the Haagse Mar(k)t at the Herman Costerstraat. It’s the biggest open air market in Europe with 540 stands. Fish, (exotic) fruits, clothes, flowers, fabrics: it’s all there. Open on Monday, Wednesday, Friday and Saterday, 09:00h until 17:00h. Be on time to avoid to crowd and bring cash. More value for your money? You pay less for most of the fish, veggies and fruits after +-15:00h.
