Four children of the late owner of the celebrated Cantonese restaurant Lin Heung Lau in Central are taking action against a similarly named restaurant run by one of the company's directors and its long-time poultry supplier. They want the Court of First Instance to stop the Lin Heung Kui from passing itself off as the Lin Heung Lau, and are also seeking damages. The four - Ngan Shun-wah, Ngan Chuen-yee, Ngan Jim-wah and Ngan Chuen-li - and the estate of former owner Yien Chi-ren filed the action yesterday against Tim Heung Tea House Limited, Ngan Chuen-fai and Wong Pak-wing. They say Ngan Chuen-fai is responsible for the daily management of the Lin Heung Lau as well as being a director of its operating company, Tien Heung Restaurant Limited, while Mr Wong has been supplying it with poultry for many years. The plaintiffs called for the three defendants to be restrained from passing off Lin Heung Kui as Lin Heung Lau and from helping anyone else to do so. They also demanded that all advertising material, menus, and uniforms be destroyed and that an inquiry on damages be made. The 70-year-old restaurant in Wellington Street is a tourist attraction famed for its 'traditional pre-war style' and the white jackets and black trousers worn by its all-male staff, the court document says. According to the writ, Ngan Chuen-fai and Mr Wong formed their company in February and opened the copycat restaurant last month. Mr Ngan told media that Lin Heung Kui was a branch of the Central restaurant, the writ alleged. But Lin Heung Lau's management and its owners, Tien Heung and Yien's estate, have no knowledge of this and have not given consent to setting up a branch, it said. Lin Heung Lau, which has operated at its present location at 160-164 Wellington Street for about 10 years, has been doing business for over 70 years and was registered as Lin Heung Tea House & Bakery in 1952. Yien died in March last year. He was the last surviving partner in the firm and had taken over the business after his younger brother died. Yien's father had been one of the predominant partners of the firm. Lin Heung Lau has been widely reviewed in travellers' guides and magazines.
