Feng Sushi, the Japanese fast-casual restaurant and take away concept backed by Luke Johnson, the serial restaurant investor, is set to return to the acquisition trail over the next six months. The company, which was established by entrepreneurs Silla Bjerrum and Jeremy Rose 10 years ago, will open its sixth site in Billingsgate in September. It is also thought to be looking at a further site in West Hampstead. The group’s current estate comprises four delivery units plus two restaurants, located in Borough Market, Chalk Farm, Fulham, Kensington, Notting Hill and Royal Festival Hall. Johnson, who heads Risk Capital Partners and has stakes in Giraffe and Patisserie Valerie, acquired the London group from majority shareholder Chris McFadden, previously an analyst with Merrill Lynch. At the time of the deal, Johnson said he was attracted to the deal as both Japanese cuisine and home delivery were growth segments in the eating-out market.
