u tell her its very easy to find...level 1 of chinatown complex, behind CK department store I think. Signboard quite big, u wun miss it.
mine I took less than 15mins, u just need to tell her what dialect group u are and what are the items u need, she will pack for u accordingly. Mine chop chop fast fast, I took liao and went off cos dun wanna squeeze with ppl. However, she's a one-man show so if there are other customers in front of u, u gotta wait hor.
