What a gem! This microbrewery is underground beneath a building in a cave brick barroom that’s hundreds of years old.  The lighting is dim, the roof is arched, and the service is amazing.  Truly it would be difficult to find a cooler brewery in the world!  It’s not a big place, but the beer had a big taste.  This is a must visit when in Oslo!  I so want to return and taste more of their craft beer and enjoy the underground cave atmosphere.
