Amy and I were lucky enough to go to the opening of the new Cha Cha Moon, at Whiteleys in Bayswater last night. Cha Cha Moon is a fast and casual Chinese noodle bar, with most dishes costing a credit crunch friendly £3.50 and is the latest culinary foray of restaurant supremo Alan Yao. It has been designed by the Japanese architect Kengo Kuma, the designer of Z58, which Camron launched in Shanghai and who also designed Yau’s pricier establishment in St James’s – Sake No Hana. With its undulating bamboo ceiling, redolent of Kuma’s much celebrated Bamboo House, the restaurant is a triumph and feels very up-market.
