Hi Choco
One of the shops in Arab Street (the only chinese selling beads there) is called "Kin Lee" (if i remember correctly), but they are opened till 6pm or 6.30pm during the weekdays. ANother one I frequent is the Indian shop, now shifted to opposit row, is called... something starting with "R" . Anyway, I have the namecards, so if u need the phone number, let me know. These shops are located behind Golden Landmark, if u coming from the MRT, u have to walk through Golden landmark lobby to the back, then u can find the whole stretch of shops there...
