Group says trading was helped by airing of Netflix documentary and opening of its 100th outlet

The UK arm of Gordon Ramsay’s restaurants empire remained in the red last year despite sales topping £100m for the first time after a string of openings in a London tower.

The celebrity chef’s UK business, which has 34 outlets including the Savoy Grill, Pétrus and several Lucky Cat restaurants, narrowed losses to £5.8m from £9.4m the year before. Sales rose 3% to almost £101m.
