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.
