hey guys, we're spending a night in amsterdam in a few weeks. our days are planned with the heiniken factory, anne franks museum and a few other places we want to see HOWEVER .... what do we do at night?

where should we visit?
where should we eat?
and nice places to have a bit of fun?

fun for two is out as its too far away and we have delayed our trip ther till april, but we want to know what naughty bars/clubs, anywhere nude friendly would be fab!
