Sandwich chain Delifrance plans to open four new outlets in the second half of the year to maintain its share of Hong Kong's $1 billion-a-year sandwich market. The expansion is aimed at increasing the firm's lead over loss-making Oliver's Super Sandwiches, recently acquired by Cafe de Coral Holdings. Delifrance's general manager Tony Yan said the expansion would increase the number of outlets to about 50. Delifrance is the major sandwich chain in Hong Kong, followed by Oliver's with 15 stores. 'Oliver's changing hands is not a pressure on us as our operation remains profitable,' Mr Yan said. Delifrance also hoped to expand its presence across the border in view of the increasing demand for Western food. Mr Yan said the Hong Kong market still had room for expansion considering the increasing popularity of sandwiches. About half of Delifrance's customers were local Chinese, he said, adding that 30 per cent were expatriates while the rest were tourists. Mr Yan said he welcomed Cafe de Coral's acquisition as the entry would help develop a sandwich culture in Hong Kong. Sandwich chain Pret A Manger is also opening its sixth shop in Taikoo Place, Quarry Bay.
