Stonegate will open its 11th Missoula bar – in Durham – in September.

It follows the launch of Rosie’s in Exeter later this week, which comprises a Missoula, Popworld and Dao.

The Exeter site is the second where Missoula has been housed with Popworld following Glasgow. A spokeswoman for the company said there were no concrete plans to repeat the format but Stonegate remained alive to opportunities.

She said: “The key is the two brands share a Gen-Y 18-21 core target demo so it makes sense to offer this “experimental” customer new things.”
