Sargeant’s Mess will be a collaboration between the former Gordon Ramsay at Claridge’s head chef, hospitality group CH&Co and the Historic Royal Palaces charity.
The 85-cover restaurant will open in the site of the former Perkin Reveller restaurant overlooking the Thames this May.
It will offer an all-day menu focusing on “modern British seasonal” plates, with dishes including smoked haddock kedgeree cake with poached egg for breakfast; Atlantic cod with dripping chips, mushy peas and tartare sauce for lunch and dinner; and daily-changing specials such as crispy Gressingham duck leg with broccoli and mash.
Tourists looking for a quick meal will also be able to order soups, vegan salads and sandwiches to takeaway from an adjoining 10-cover cafe-deli.
The 40-cover outdoor terrace bar will serve prosecco on tap, frozen cocktails and beer slushies during summer, and Sargeant has chosen a selection of “affordable” wines, beers and cocktails to match the food.
Sargeant’s Mess is the chef’s first venture in to the London restaurant scene since he closed Soho restaurant Morden & Lea in 2016 after just a year.
The chef, who won a Michelin star while at Claridge’s, also oversees the menus at the Plum and Spilt Milk at the Great Northern Hotel in King’s Cross and runs four restaurants and gastropubs in Kent.
