Two new restaurants in Central's trendy SoHo district are seeking to challenge controversial licensing conditions which require them to keep doors and windows closed after 6pm and forbid the sale of alcohol after 11pm. The owners of Boca and Amida have appealed against the extra conditions set by the Liquor Licensing Board for all bars and restaurants in the area. After a two-hour hearing on Friday, the chairwoman of the Municipal Services Appeal Board, Madam Justice Maria Yuen Ka-ning, ordered the Liquor Licensing Board to disclose all documents explaining how it came to set different liquor licensing conditions for businesses in SoHo from those in other areas. The hearing was adjourned, but no new date was fixed. Boca and Amida, which have been operating for just a few months, are on Peel and Staunton streets respectively. Both streets, as well as Shelley and Elgin streets, are widely known as SoHo by locals. SoHo and Yiu Wa Street in Causeway Bay are the only areas subject to the extra conditions. For bars and restaurants in the Causeway Bay street, licensees are required to ensure nobody drinks alcohol on their premises after midnight. For all other areas in Hong Kong, bars and restaurants are generally required to follow only standard requirements, such as not permitting prostitution, gambling or dancing, and keeping toilets clean. Extra conditions may be imposed by the Liquor Licensing Board on a case-by-case basis, according to a spokesman for the board. In a statement, the board said: 'The rationale for imposing additional conditions to the area is that the board must strike a balance between the business interest of food/beverage outlets and the interest of nearby residents with due regard to the nature of the locality . . . the likelihood of nuisance being caused, and the effects of liquor consumption on the peace and order of the areas. 'Applying these conditions is a good compromise to ensure liquor-selling businesses can be operated in a small, tranquil residential community with the least disturbance to residents nearby,' it said. There has also been an ongoing dispute over street signs bearing the name SoHo, which have been barred because some residents fear people will associate it with the seedy past of London's Soho. But business owners in SoHo seek to promote the area by using the name to attract tourists. There are about 50 bars and restaurants and 150 shops in the area.
