If you've got time to kill in the afternoon's take a water taxi from the other side of the bridge adjacent to Centraal Station and take a leisurely cruise around to the Heineken brewery it's great. Stay clear of the Bulldog Cafe's, and find an Argentinian Steak house for the best steaks i've had outside Brazil and Australia. The red light district will be eye-opening especially the dark and dingy corners of it, the ladies range from Victoria's Secret to women who probably should carry a health warnign for your eyes and health. Enjoy.
