Borealis will launch in Borough on 7 August in conjunction with co-working space developers Fora.
The new venture will comprise a work space and private room for hire on the fifth floor; and a ground floor restaurant and café area.
Heading up the kitchen for both the restaurant proper and the café will be Swedish-born chef Robin Freeman.
The restaurant will serve Nordic cuisine, with the starters menu including the likes of snaps-cured mackerel with juniper, orange, dill and shaved fennel; and smoked ox tongue with sea buckthorn, pickled beetroot, allium flowers and rye crumbs.
Main courses will include veal and pork meatballs with mashed potato, lingonberries and pickled cucumber; lamb cutlets with potato, shallot, herb and sprat salad; and roast cod with brown butter and cauliflower.
The café area, which will provide take away options, will be accessible through a separate entrance and will serve Danish pastries; open-face ‘smorrebrod’ sandwiches; and Allpress coffee.
Within the restaurant, a 20-cover bar will serve both classic and Scandinavian-inspired cocktails; and a 50-bin wine list.
“Borough has become such a vibrant, exciting and energetic area of London - and what Fora have created with this new site, just 300 or so yards from Borough Market, is absolutely suited to the neighbourhood,” says Jessen.
“We are delighted to partner with Fora to launch a restaurant, bar and several private events spaces within their new building - all of which are a celebration the very best of Nordic food, drink and design.”
Jessen, previously a banker, owns fine dining bar and brasserie 1 Lombard Street, and launched Ekte Nordic Kitchen in the Bloomberg Arcade earlier this year.
