Domino's Pizza has said it is benefiting from continued economic recovery in its markets, especially in Dublin.
In an interim management statement, the company said that Irish like-for-like sales grew by 5.3% in the 13 weeks to September 28.
The firm has also been boosted by demand for its mobile app and revamped website, which customers are increasingly using to order their pizza.
Almost 71% of delivered sales were placed online in its third quarter, up from 62.4% a year ago.
Domino's also posted sales growth at its Swiss division but said progress in Germany, where its much-anticipated expansion plans have been hit by restructuring costs and weak trading, remained slow, with sales down 9.9%.
It has slowed German expansion while it gets to grips with store formats, menus, overheads and growing sales at self-managed outlets.
The group said today it was on target to open 40-50 UK stores by the end of the year.
Domino's said that while it faces more challenging comparatives for the final quarter, it remains confident of a satisfactory outcome for the year.
