邊度有得買番紅花絲?

I've bought this 番紅花絲 at [ Taste ] supermarket in Stanley Branch.
It might be available in Kowloon Tong branch ??

我曾經在西寶城的wellcom 超級廣場見過有得賣,
或者可以去中環太子大廈的oliver supermarket有沒有?

Are you talking about "saffron threads"? If so, you should go to the Indian grocery shops in Chung King Mansion, Tsim Sha Tsui. Or you can buy it in Oliver's Delicatessen.

Chung King Mansion is on Nathan Road where there are many Indian restaurants. Indian use this spice a lot. Ask an Indian where to buy it if you dont know where it is.
