This is such a wonderful place with a marvellous atmosphere! Haven't eaten there yet (they offer raw food only), but when I was in Amsterdam I used to buy fresh juices (many options to choose from) or their rich Breakfast smoothie everyday, which are prepared right in front of you. A smoothie/juice costs about 6,-€, but it's absolutely worth the price! They also sell super foods and other raw basics. The staff is really friendly and I loved the way how warmly they welcomed us. Would go there anytime again!
Cons: Expensive (worth it, though)
