Ping Pong, the dim sum chain led by Jean-Michel Orieux, is to operate a pop up version of Now, its smaller takeaway style outlet, at this week’s Royal Ascot in Berkshire. The company, which operates 12 standalone restaurants, will operate the pop up unit across the five-day horseracing festival that starts tomorrow. The group, which is led by Jean-Michel Orieux, opened its first Now site opposite Liverpool Station in London last year, and industry observers there is more mileage in this format than in its core estate. The company is on the verge of opening its second site in the US, in Washington DC. The group has taken a site in the Dupont Circle district, a well-known entertainment area with a substantial mix of bars, restaurants and nightclubs. Ping Pong made its debut in America just over a year ago. Ian Daly, the former Compass executive, is heading up the company’s American foray.
