In November, Hong Kong’s central business district appears likely to lose another establishment popular with the locals to accommodate hordes of mainland Chinese shoppers craving luxury goods. The popular eco-supermarket ThreeSixty, occupying 30,000 square feet on two floors in The Landmark in Hong Kong’s central business district, may be about to close, say reliable sources connected to the Dairy Farm Group, which owns the space. The decision to close is still under active consideration, some sources say. Others do not see it that way. If the closure goes ahead, plans are for the space to be given over to a special area selling luxury brands, fashion and accessories designed to appeal to mainland shoppers.
