There is always a line! But it's quick (they usually have 3-4 people working) and well worth the 8 min wait! The frites are cooked to perfection and the mayo and samurai sauces are delish! A must visit, especially if it's your first time having frites in Amsterdam! Their mayo is different than US mayo, so eat like a local and give it a try, your tummy will thank you for it! Check their times though! They close earlier than any of the other frites shops!
