Opening in Fenwick’s multi-million pound Food Hall, the restaurant will open in early October.
There will be seating for 23 covers at the counter and it will have an open kitchen.
Among offerings on the menu will be Salt and Pepper Squid, Seafood Cocktail and Crab Sandwiches, accompanied with a fish-focussed wine list.
Laybourne said: “Our chefs will work hand in hand with the fishmonger, taking a ‘we cook what we sell, we sell what we cook’ approach. Fish is seasonal so both our fishmonger and menu will be constantly on the move, reflecting the rhythm of the season.
“Due to our network of suppliers and producers that’s been developed over many years we will only select the best of seasonal seafood and go wherever it takes to find the best. Our fishmongers will ensure we consistently offer the finest, highest quality seafood that comes from the fabulous larder off the North East coastline as well as other ports around the UK.”
Laybourne has also announced the £100k refurbishment and rebrand of 21 Hospitality Group’s flagship restaurant Café 21 which will take place between 23rd August and September 8th.
