The Restaurant Group (TRG) has continued to make "good progess", reporting a 9.1% year-on-year increase in total sales for the 45 weeks to 10 November 2013.
The company, which owns the Frankie and Benny's and Chiquito brands, said that like-for-like sales were up 3.5% for the same period, in line with expectations.
TRG opened 21 new sites to date in 2013, with a total of between 33 and 35 new restaurants planned to launch by year end. The company said the new openings were performing well with strong returns expected and that it anticipates opening more new restaurants in 2014 than in 2013.
The announcements were made in an interim management statement ahead of the close of TRG's financial year on 29 December.
"Since our interim announcement at the end of August, the Group has traded well, with like-for-like sales growth in both September and October," the statement said.
"Although the like-for-like comparatives are much tougher during November, we are confident that the business will continue to make good progress during the remainder of the year and we are on track to meet expectations for the full year."
