Bladestorm, our resident HKG member also posted a bit on shopping in her intro thread.

With some of the speciality stores, they do not open till later in the arvo or only in the evening. Quite a number of toy stores are located in Mongkok from memory but can't recall where they are. For morning shopping, the TRU in Ocean Terminal is open.
