Michel Roux is to oversee a new restaurant and cocktail bar at the Crossbasket Castle hotel on the outskirts of Glasgow.
The restaurant, named Trocodero's, will open in August and feature live music and entertainment seven days a week.
It will be the second Roux restaurant at the hotel, which has worked with the family since 2016.
The late Albert Roux originally oversaw the menus at the Crossbasket hotel restaurant, and the responsibility has now passed to his son, Michel, while the hotel's executive head chef runs the restaurant on a day-to-day basis.
Announcing the news in the Le Gavroche email 'Rouxletter', Michel said: "Trocodero's is going to be the talk of Scotland! Fabulous, tasty food, great entertainment and somewhere people will want to keep coming back to.”
The 17th century Crossbasket Castle is part of the Inverlochy Castle Management International (ICMI) collection, which works with the Roux’s across several of its other luxury hotels including Inverlochy Castle near Fort William.
Crossbasket has been owned by Steve and Alison Timoney since 2011, a year after it was listed on Scotland’s Buildings At Risk Register.
The couple spent £10m restoring the property before it relaunched in 2016. A further £15m expansion, which will see the addition of 40 new bedrooms, a spa, eco lodges and the new restaurant, will open to the public this summer.
