The black vinegar is more sweet than sour but there is a bottle of vinegar on the counter for customers to help themselves to for a sharper taste. Chef Sham uses the Chan Kong Thye (aka doggy brand) black sweet rice vinegar which he proudly displays all over his stall.
This collagen soup is comparable to those that you have in Hai Di Lao or Beauty In a Pot but I would choose Chef Sham’s soup over those any day for its affordable price!
