London-focused Edwardian-style restaurant operator Richoux Group will not be opening any new restaurants under its own name in the near future following a disappointing performance from new openings.In the 28 weeks to July 12, pre-tax losses fell to £992,000 from £278,000 over the same period the previous year as revenue fell to £2.7m from £2.9m.While the Richoux restaurants in Knightsbridge, Mayfair, St John's Wood and Piccadilly have continued to trade well, new openings in High Wycombe and Old Compton Street have traded well below expectations.'The disappointing performance of the most recent Richoux sites means the group is not foreseeing further expansion of Richoux at present,' the firm said.However, it is opening a restaurant called 'Zippers' in Chatham, which is to be 'a mid-market family orientated concept with a wide food offering.'
