Amsterdam is one of the most inviting cities to people who choose meat-free meals. Even if the restaurant is not dedicated to vegetarians or vegans, there is a good chance the place can easily cater to these customers' preferences. It is one of the best moments to come to Amsterdam for the ones who crave meals in which vegetables are the star of the show.
The way the Dutch have been interacting with food is completely different from what it was four years ago. And way much better! I apologize to my Dutch friends, but the truth is their gastronomy used to be one of the less appealing in the world. Some food habits are hard to understand, but they justify this issue.
