Several topless bars, peep shows and sex show clubs in Amsterdam's famed "Red Light" prostitution district have declared an open house on Feb. 18, hoping to shore up their reputation with local politicians who are calling for a crackdown.

"You can come in, have a free drink, look around," said Bob de Maan, spokesman for the "Banana Bar," which is known for its live sex shows.

"People think that this is something dirty, but now — it's an open house. They can see for themselves."

The open house came in response to proposals by the head of Amsterdam's largest political party meant to discourage women from marketing themselves in windows.

Several of the best-known institutions are opening their doors, in an idea supported by the Prostitution Information Center, the Sex Museum, and the Salvation Army which helps the district's many downtrodden.
