Olivia,
D’ Vijff Vlieghen or The Five Flies used to be one of the very top top restaurants in Amsterdam (maybe still is). With all the Dutch influence in SA perhaps it's named after that!
Anyway it looks good!
Editing to say yes, it is the sister restaurant to the one in A'Dam. And, hmmm, I'm thinking with the prices for the 2 and 3 course menus, the price for the oysters etc. may be a supplement!
