Bring your dancing
Why locals love it?
The music reflects the latest development in electronic dance music from Europe and the crowd is arty and hip. Time stands still and the "beer flows like wine [and] beautiful women instinctively flock like the salmon of Capistrano."
Why you should visit it
To discover the true Icelandic nightlife, this might be your best bet. You might have to show up early, unless you meet up with some hip Icelanders who are on a talking terms with the doorman - as that might help you escape the ridgid waiting line.
Things tend to get crowded, so a bottled beer might avoid spillages.
