several: "Some kind of pub crawl..." Porsgrunn Nightlife Tip by Saagar

There are a number of brown pubs that attract a somewhat sombre clientele here. The places seem to have their own sort of clientele with small tribal differences. However, the discern all these seems difficult, manageable only for locals. A pub crawl could be an interesting option here.
Eigil's Pub seems interesting, especially by the look of the lady poster inside (seen through window). I was denied access by my companion because of this!

Dress Code: Dress in black, dig heavy metal music and leave your hair long and straight.
Well, just by the look of it.
Anything goes, I suppose, as long as you are class conscious. This is a working class town - presumably also by culture.

Directions: Storgaten seem to have a few pubs and eateries open at night. Some live music, and even karaoke (that place - no name mentioned - had two customers).
