THE place to go is TakeToys.hk
https://taketoys.hk/
I am pretty much VIP when going to several of those shops...as I bought many things, mainly clothes, for ladies there since 2021!
The most comprehensive places with several shops in CWB, Central, SSP, Jordan,...everywhere in Hong Kong!!
From experience,
* Check first on their website!
* Then for the items that you want, ...do check in which shops they have inventory,
* Print out the reference of the items (saves time),
* then go to the shops to buy.
THE shops with largest inventory and friendly staff:
* CWB Jardine's Baazar!
* SSP near MTR, 133-135 Kweilin St (maybe bigger than CWB)
Large inventory and very friendly helpful staff.
(When a gweilo walks in with a Chinese walk-up and they leave with a big bag of clothes, ...when you come back, you have all their attention..and discount!)
Hollywood Road shop is good, but less choice. Friendly staff.
Jordan shop is convenient ...when seeing somebody in KSM.
Wanchai: very small inventory
CWB Lee Garden Road shop: AVOID. Small shop with staff that does not give a shxt!!
(once I had to get assistance from CWB Jardine's guy to buy something in Lee Garden Road!! )
Have fun.
