Food trucks or food stands in Amsterdam are hard to find. Most of them will either sell hotdogs or ice cream. It has something to do with a law here but recently this law has changed. A lot of people are hoping to find more food trucks at street corners but for now, the foods tands at Waterlooplein do the job.
Mostly a market for vintage clothing, jewelry, second hand electronics, bikes and some marijuana souvenirs, the back of the market has changed into a little food valhalla. Ranging from Japanese pancakes (okonomiyaki), Greek souvlaki, Vietnamese spring rolls (the fried version) and Dutch pancakes, you are sure to find a cuisine to your liking. The Vietnamese spring rolls are so good, they deserve their own page. The Japanese okonomiyaki might be new to most palates but it sure deserves a try and the owner might throw in a free cup of matcha tea.
Opening hours are irregular since some shops are closed on Monday or Tuesday, but I am sure you can find something you like. If the stand of your interest is closed, all the more reason to go back another day and try something else!
