The Grand Union Group, the operator of the burger bar and cocktail lounge concept, is to launch its first site outside of London in Buckinghamshire in spring 2009. The company will open its fifth outlet in Stoke Hammond in partnership with Scottish & Newcastle next year following a £500,000 refurbishment. The group, which was founded in 2006 by Adam Marshall and Adam Sandford, said that the site would be more food-led than its London outlets. The new venue will be rebranded as The Grand Union Bar & Grill instead of the Classic Burger Bar and Cocktail Lounge as the other sites are known. The partners are looking to focus their expansion on national sites after finding it difficult to secure freehold properties in London and are interested in a new pier development at Chatham, Kent.
