Scotland's fine-dining restaurant scene has taken two steps forward and two steps back in the 2015 edition of the Michelin Guide.

The 2015 guide awards a new Michelin star to the Three Chimneys on Skye and the Isle of Eriska at Benderloch, Argyll, while deleting those for Glenapp Castle in Ballantrae, Ayrshire, and the Inverlochy Hotel near Fort William.

The total number of single Michelin starred restaurants in Scotland remains at 15.

Restaurant Andrew Fairlie at the Gleneagles Hotel retains its position as Scotland's only two-Michelin starred restaurant. Two stars means "excellent cooking, worth a detour".

Glasgow, meanwhile, has triumphed in the increasingly popular category awarded for good food at affordable prices. The Ox and Finch and The Gannet, both relative newcomers and both situated in the fashionable "Finnieston Quarter", have each been awarded a Bib Gourmand, bringing the city's tally to three along with Stravaigin.

Edinburgh also gains a third Bib Gourmand for Passorn Thai restaurant, which joins Dogs and Galvin Brasserie de Luxe.

In an exclusive interview Rebecca Burr, editor of the Michelin Guide, said that while stars are still the most important part of the Guide, there has been a new focus on value-for-money establishments this year.

She said: "The Bib Gourmand awards reflect the continuing trend for competitively priced, less structured and more flexible dining, and are a growing part of our collection as diners become more and more cost-conscious.

"This trend is well reflected in Glasgow, where young chefs of this exciting new generation are proving they have a firm grounding in good quality food and are passionate about it. We want to encourage more young chefs to use Scotland's world-class produce simply and well."
