Hi John:
I don’t know of any Yellow Pages equivalent; mostly found shops by roaming the main streets w shops, wandering in n giving them a try.
To me, Cheung Chau Furniture store (towards Pak Tei Temple) is good; can help w delivery, putting furniture together (and, in case of our wardrobe lately, even help take it apart!) – which you don’t get w IKEA. Folk living here may be able to recommend other shops.
