There was a lot of quick street food to grab while walking around Amsterdam (herring, for instance). Fries + sauce counted as lunch a few days. These were from Vlaams Friteshuis Vleminckx, the best Belgian fries from Amsterdam.
This place is basically just a hole in the wall with a walk up line (which is always full). They make the fries as the customers order. Zed and I ordered some with Belgian mayo (not sure how that’s different than “the classic mayo,” but it was delicious) and Andalouse sauce, which was more tomato-y. I saw it described somewhere as “kind of like thousand island.” A few days later I went back by myself and got the yellow curry sauce, as seen in the photo up top. It reminded me of the chicken curry ‘n fries I used to get at St. Stephen’s Green in Mountain View.
Their menu doesn’t really go into what makes each sauce, unfortunately. What is Hannibal sauce? WHAT IS IT.
