The Struis is really good and they have an IPA and pale ale I have been trying to find locally but not had much luck.
Made a trip up the the Brouwer 't IJ tried out three of the beers the IPA, Columbus and Motueka Pale Ale.
Came home with a couple of cases, wish I would have gotten a case of the double IPA. Anyway its easily some of the best beer I've had over here and it's a busy cool pub. If you are in A'dam I would definitely give it a try.
