The Diner, the US style restaurant concept operated by the Barworks Group, has closed its site in Covent Garden, MCA understands.

The Shaftesbury Avenue site is currently being converted to new Moorish cuisine concept, Beso.

Beso is the brainchild of Khalid Dahbi, who runs Q Café Chic in Portland Place. He has previously worked for Gaucho and the Jamie Oliver group.

There are now seven Diners in the capital. The group closed its only regional site, in Southampton, in February.
