We love having ramen here - it's a beautiful space, feels a bit like being back in NYC, and the food is incredible. There are two locations, the one in De Pijp is bigger, so easier to get a table, but the other location is very cosy, so get there early if you go to that location.
The fence around De Nederlandsche Bank on the Frederiksplein is a true optical experience. While passing the building, a rhythmic, dynamic pattern appears and disappears in the trellis of the fence. The figures on the sides of the rails were designed in 1992 by artist Peter Struycken, a pioneer in the area of environmental art and generating computer-program based image, light and colour compositions.
Hannekes Boom is one of the nicest waterfront café in Amsterdam to have a beer when it's sunny. Close to Central Station, the place isn't crowded by tourists, but you need to be there early to get a seat.
Not a big fan of zoos and animals behind cages, but if you can spot Flamingos in the east-centre of Amsterdam, then count me in <3 ! You can actually see them while riding the bike on Plantage Middenlaan, quite a beautiful scene.
Note: De Plantage next to zoo is quite cool cafe/restaurant, with a mix of vintage style and industrial elements of the old buildings of Artis. Great atmosphere, and ideal for a more sophisticated outing.
