We saw Trio of Oz at Jazzhus in October 2011. The show was great; the space is cozy and appropriate. There were 50 to 60 people in the audience.
We had dinner at the club before the show. That we would not recommend. The food was alright, but not terrific and there were few other diners. There are plenty of cafes and restaurants in the immediate vicinity. If we go there again we'll have dinner elsewhere then catch the show.
The audience was friendly and welcoming to the musicians. Everyone was happy to be there.
Jazzhus was a signature club in the jazz circuit in the 50's and 60's but closed for years. It has been reopened in the original space with updated frunishings.
We don't usually go out in the evening, except for dinner, this was an exception to our routine and well worth it. The couple in front of us. local Copenhagers, were friendly and talkative during the intermission. The players circulated in the audience during the intermisison as well. Very intimate and pleasant. A high point of our visit to Copenhagen.
