Over the last forty years, The Ubiquitous Chip has played a central role not only in the culinary history of Glasgow but also in the revitalisation of the city's West End and the establishment of Glasgow as an international arts capital. To celebrate its anniversary, Martin Gray tells the story of the Chip and its inspirational founder, Ronnie Clydesdale, who revolutionised the restaurant scene in Glasgow and made the Chip one of Scotland's best known restaurants.
