Herr Nilsen sits on C.J. Hambros plass 5 in central Oslo, a narrow music pub that has booked live jazz and blues almost every night of the week since 1993.
The club takes its name from founder Espen Nilsen, who opened it to fill the hole left when the legendary Oslo venue Club 7 shut in 1985, per the club's Wikipedia entry. More than three decades on, the booking policy has not softened.
Who would love it: a listener who wants the band an arm's length away and a calendar that runs concerts most nights of the week. Who would not: anyone after a quiet table to talk over, because the room is built around the stage and the music wins.
The space is small and low-lit, with the stage set near the windows and the bar running down one side. Capacity is modest, so a name act fills the room early and the front tables go to the regulars who turn up before the first set.
The programming leans hard on New Orleans and Dixieland jazz, with national and international names rotating through the week, as VisitNorway notes in its listing. The calendar on the club's own site is the document to read before going, because the bill changes nightly and some sets carry a cover.
The move is to check the night's act, arrive before the first set, and drink simply. The bar runs beer and straightforward cocktails rather than a long menu, which keeps the focus on the stage. Cover charges vary by act and are listed per show on the venue site.
The crowd is a mix of Oslo jazz regulars and visitors who have done their homework, weighted toward people there to listen rather than to be seen. Reviewers on Yelp and Restaurant Guru return to the intimacy of the room and the quality of the bookings as the reason to come.
Best time to go is a weeknight when a touring act is on the bill and the room is full but not packed. Pair it with a wider night out across the centre, where the Blå jazz club down by the Akerselva runs a louder, later programme.
The history is the draw worth understanding. Herr Nilsen has outlasted most of Oslo's small live rooms by keeping a single focus, live acoustic and electric jazz in a room sized for it, rather than chasing trends. That consistency is why the city's musicians still treat a booking here as a marker.
For the drinker, the appeal is the trade the room makes: a short bar list and a cover charge in exchange for a front-row seat at a working jazz club. It is closer to a concert than a night at a bar, and the regulars price that in.
The bar itself stays deliberately understated. There is no long cocktail programme and no kitchen to speak of, which keeps the overheads low and the door prices modest for a venue that books working musicians most nights. The drink is a means to the music, and the pricing reflects a club that funds itself on the bar and the cover rather than on food.
For a visitor planning an Oslo jazz night, the move is to pair an early set here with a later one elsewhere. Herr Nilsen's first sets often start around 8pm, which leaves time to move on to a second room, and the central spot near the Tinghuset makes that easy to do on foot.
