Been traveling in Spain for a couple of months, and I've seen plenty of bars pretending to beer houses.  Etxeberria in Donostia-San Sebastian is the real deal.  It's all about the beer in this hole-in-the-wall.  With 2 dozens taps, you'll find plenty of local craft beers.  I arrived at the end of "Semana Grande", a week long festival, to find the beer stock low, but still great.  Nothing fancy, just great beer!
