Halvorsen's Conditori was established in 1881 and thus has a long tradition as a Viennese confectionary. The establishment offers a varied selection of both classic and modern cakes, as well as sandwiches. The patisserie has recently undergone a refurbishment, where emphasis has been placed on continuing the traditions that have characterized the place over the years.
The interior is decorated by local artists, including Live Haug Hilton, Hanna Duna and Kim Andre Hagen, which gives the venue a unique feel. Halvorsen's Conditori is known for its opening celebrations, where cake, champagne and soft drinks are served. This contributes to a festive atmosphere and a celebration of the patisserie's history and traditions.
