The pair say they are looking for a more central location for their Scandinavian restaurant and bar, which opened in Prestwich Village in 2000.
Writing on Instagram they say: “It’s with a heavy heart, but excitement for the future, that we have decided to close our Prestwich restaurant ahead of a move to the city centre.”
“Being fully transparent - we’ve struggled to find experienced staff, leaving us with little to no personal life. We have made the decision to move on to what we hope will be a more sustainable business that can grow, and allow us more time to follow our dreams. This is by no means the end of Osma.
“We’re optimistic, but it’s bittersweet. After (almost!) five years we have met so many amazing and incredible people, who we’re proud to call our friends and Osma family. So many of you have kept coming back week after week - we feel honoured and so grateful for your company.
“There have been hard days over the years and your kindness, patience and good moods have made such an impact on us to keep pushing forward. Thank you!”
Osma’s name is a portmanteau of Oslo and Manchester, where the pair grew up.
The restaurant’s last service will be on 9 February and the pair say that any gift cards bought after that will be refunded or extended to use at their new site.
The pair’s Kitchen at Exhibition on Peter Street will remain open as usual.
