The city's biggest flea market is hosted the first weekend of each month in and around a gigantic warehouse in the industrial area of NDSM in Amsterdam Noord. I love to snuff around the hundreds of stalls to find unusual props. Taking the boat to cross the IJ and leaving the old centre behind is very refreshing. Make sure to also have a drink in Noorderlicht while the sun sets.
I love to discover, explore and destroy photo books with my eyes and subsequently my portable telephone. A place where I love doing this is in the Stedelijk Museum. Yes, gift shops are typically stocked with pure Dutch gouda like any other gift shop but I find with enough dedication there is something to be found. I particularly enjoyed this one. Perhaps it is my Dutch affinity for milk.
Just Indulge yourself with a glass of wine while watching a good movie. Really cute art deco movie theater in the Jordaan packed with film lovers. The rooms are not that big but the atmosphere is amazing.
