This is a good place to start the evening as the beer and wine is fairly cheap (if there is such a thing in Iceland). The crowd is young and the atmosphere is quite calm and friendly. Sports are occasionally on screen and the chairs are comfy.
This place is positioned at the university campus and is therefore a little getaway from the central scene. As mentioned before the alcohol has a "european price" and the crowd are mostly university students in their early 20's.
Tip for the sport fan: They show soccer on a big screen during game nights.
