Yip, Dutch beers instead of Belgian beers for a change!  What a great place, it stocks beer from Dutch breweries only and a hell of a lot of them, more than 130 with loads on tap and seasonal ones as well.  The bar snacks are good too, for when the high percentage alcohol beers hit a little hard!  The bar staff are extremely knowledgeable and will take the time to discuss the right beer for you.  Don”t try and order from the menu, rather explain what sort of beer and flavour you want, how light / dark / bitter/sweet.  I could live in this place actually, I think I will.

They have an English version of their website along with a streetmap link so you can find it..
