Vegetarians should not have any major trouble. 4.5 percent of the Dutch population is vegetarian and most restaurants have at least one vegetarian option on their menus or can make you one if you ask for it. Most supermarkets sell vegetarian products or even have a part of their supermarket dedicated to vegetarian products. It is advisable to specifically mention what you do and do not eat (meat, fish, dairy, eggs) as not everyone has the same definition of vegetarianism. Finding a vegetarian option in a fast food restaurant might provide more of a challenge. Chip shops that sell veggie burgers are the exception rather than the rule; chips and kaassoufflés are often the only options.
