Novus Leisure, the privately-owned bar and club group, has relaunched four of the former Balls Brothers sites it acquired in march this year. The group, which invested £240,000 in refurbishing and relaunching the Balls Brothers site in Lime Street as the Lime Street Exchange, has now carried out similar projects on the units in Bishopsgate, Mayfair and near Monument. Each carries the Exchange moniker with the Balls Brothers branding secondary. M&C Report understands that consultant James Spragg, former chief executive of Yellowhammer Bars, is advising the company on the revamp programme. The group’s aim is to widen the current customer base of City professionals to all those working nearby.
