Opening in winter 2016, the new all-day dining concept will serve a mix of freshly baked breads, cakes, Scandinavian flatbreads, soups, stews and ‘luxury sandwiches’ at 56 Haymarket.
The menu will also include single estate coffee and a small wine and beer list.
It is the brainchild of Ole Kristoffersen and Steen Skallebæk, whose bakery chain Lagkagehuset has over 50 sites in Denmark.
Ally Gordon, of Ole & Steen, said: “London is such a cosmopolitan city, and such a foodie city, that we know it’s absolutely the best place to plant a flag for Ole & Steen outside Denmark.
“We know that it will very quickly become the new, exciting destination for both London foodies and lovers of quality from overseas. We can’t wait to fire up the ovens!”
The restaurant is the latest addition to the £400m St James’s scheme, which is being developed by The Crown Estate and Oxford Properties.
Other restaurant concepts confirmed for the site include Japanese brasserie Anzu; Veneta, a Venetian-themed eaterie from the Salt Yard Group; and the first UK outpost of New York’s two Michelin-starred Nordic restaurant Aquavit.
