Some say that the best entertainment you can get in Amsterdam is at the Red Light District where you can basically have the time of your life. Since prostitution is legal in Amsterdam since 1815, low cost entertainment, even of the erotic kind, is readily available. There are also street performers and bands performing live in cafes and bars to lighten up one’s day.
You may also like to visit the sex museum whose displays are quite informative and sometimes offending to others. For other types of entertainment, you may go to the movies, the bar and even attend cultural presentations.
