Seven out of 10 seafood restaurants and stalls in Lei Yue Mun have seen revenue drop by more than half over the past year because diners have cut back on expensive dishes, a survey found. The Democratic Alliance for the Betterment of Hong Kong surveyed 57 restaurants and stores in the seafood port last month. The survey also found that food stalls and stores had seen income cut by 70 per cent. Two-thirds of the surveyed shops said business was 'very bad'. Seafood restaurant owners said running costs were high and the number of customers had fallen significantly amid the economic downturn. Consumption among locals and tourists was weak. More than 40 per cent of the shop owners called on the Government to provide more parking to attract customers. Other proposals include building a new public pier, renovating historical buildings and maintaining roads. The party said the Government should organise more special events and put up extra decorations during festivals. In the long-term, it said the Government should consider a museum on the history of Lei Yue Mun.
