They just opened this in my city.
http://www.taphuys.nl/
24 beers and 14 wines on self tap. 80 beers in bottle.
While it seems like fun to visit once or twice, like those places with 50, 70 or 100 beers on tap, it's a bit gimmicky.
I prefer the smaller places that really care about offering good beer and have a knowledgable staff. Luckily there are a lot of such places in this part of the world.
In my city:
Kandinsky
8 beers on tap, over 200 in total.

Burgemeester Jansen
15 beers on tap, over 100 in total
