Located under Q-Park, Waterkant is ideal for sunny days since you can get direct sunlight until late evening. Grab a beer and a table on the terrace and enjoy sunny Amsterdam while it lasts.
Note: if you get a bit tipsy you think you see a double Guggenheim
OT301 is a cultural centre in the former building of the Film Academy at the Overtoom. It’s a good place to get drunk, watch a movie or to eat. It's not too expensive, like most other places in Amsterdam, and the ambience is good.
Hidden in the greenery near Westerpark, the perfect hideaway from street noise can be found if you know where to look: a little farm called "De Buurtboerderij". Surrounded by a bunch of sheep and a happily decorated garden, the restaurant inside serves one fixed menu a week for a low price. The farm serves as community center as well and is run by volunteers — and you when you eat there! — and there are plenty of sweet people and animals to hang out with.
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.
It's a very small museum in the Hermitage about art made by outsiders. It's also known as 'Art Brut', a name given to it in 1972 by French artist Jean Dubuffet. It simply means that it is art made by people that don't fit in the normal life structure that humans suppose to have. Which can mean that the art is made by people who are in jail, who are ill, have a mental dissability or another way of not fitting into the community. The exhibitions are quite small, so it takes you just around an hour. And the hermitage has a nice canal view.
