Have been twice a year for past 5 yrs.
Best Museum - Rijksmuseum, unrivaled collection of artwork almost as great as the Louvre in Paris, original oils of the Masters. Rembrandt's NightWatch is haunting, VanGoghs, Matisses, Jan Steen, Vermeers, Mannets, Monet's Water Lillies on display there. Van Gogh Museum is good but no comparison IMO.
Best Brothel - Yab Yum

Next best Brothel - Golden Key Club
Best Coffee Shop - Grasshopper near Central train station.
Best hotel - Kraznapolski
Best Show - The Banana Bar XXX
Best sightseeing - by boat in Canal Cruiser
Best Casino - Holland Casino near Leitsplein, but the action inside is like a morgue, the patrons are so stiff its like they put viagra in the coffee, no one raises their voice or gets excited, I was asked to leave when I tried to get them to liven up a little. Nice looking croupiers though.
Best transportation - the trams or trains cant be beat, schedule board is most confusing and intimidating, just ask for help.
Biggest tourist trap - Anne Frank's house unless you like standing in line in the rain to be herded through a piece of shit.
Best Movies - Tuschinski theater, fabulous throw back Art Deco building, like the good old days, smells like opium inside, good place to catch a double feature.
Best Food - Amsterdam is not noted for food. If you get the munchies however "Walk around and let your nose be your guide."
