Time Out says
Popular supermarket chain all over Hong Kong
Wellcome is one of the largest supermarket chains in Hong Kong, with stores all over the city. Smaller stores are super convenient and stock a wide range of fresh fruit and veg, fish and meat, as well as Asian and Western staple dry goods. Larger stores have a much wider selection, including live fish tanks, in store bakeries , deli counters and grind-it-yourself fresh coffee bean dispensers.
