The group, led by Mark Derry, intends to use the investment by Core Capital to develop new sites across the brands.
“This capital injection will allow for more rapid expansion of our brasserie businesses and is testament to the resilience of our existing restaurants which are trading well and providing good returns on investment,” said Derry.
“We believe that this market is robust and offers good growth opportunities.”
The group, which opens its headquarters in Teddington this month, currently operates nine Brasserie Blancs in Bristol, Cheltenham, Chichester, City of London, Leeds, Milton Keynes, Oxford, Portsmouth and Winchester.
Its pub arm the White Brasserie Company, which launched in August 2010 in Teddington, has a second venue in Weybridge.
“While by no means immune to difficulties in the wider economy, operators in the premium casual dining sector who are able to offer quality of service and product continue to perform well,” Derry continued.
“This, combined with the trend for eating out which has become an established part of day to day life in the UK, means we are well positioned to roll out the business.”
The group have also announced the appointment of former Loch Fyne Restaurants chief finance officer Helen Melvin as finance director.
She will sit on the board alongside managing director John Lederer and chairman Ian Glyn.
