Buying Wagamama has had a transformational effect on the fortunes of The Restaurant Group, said the business as it released its results for the 52 weeks to 29 December 2019. It said total sales were up 56.4% from £686m to £1,073.1m, while adjusted pre-tax profits were £74.5m. It recorded an exceptional pre-tax charge of £111.8m due to “impairment” in its leisure arm, primarily made up of Frankie and Benny’s and Chiquito, leaving a statutory loss before tax of £37.3m.
