Parkteatret is located in a prime spot at Grünerløkka, an area of Oslo that has moved steadily upmarket for the last two decades or so. Young and quite affluent population, spending lots of their time hanging out with friends in bars and cafes.
Parkteatret was a movie theatre in a previous incarnation, now it houses a concert venue that is also used for the taping of some TV shows. The old lobby area is a bar open daily, and they have a decent range of Norwegian micros. They have the full list of Haandbryggeriet beers, including their Weizen on tap, and there are some Nøgne ø beers available, too. Decent prices for here, all beers well below the 100 kroner mark. No food, but there are good options nearby.
