Just posting having visited the very recently opened Warhammer Store in Hong Kong:
https://www.facebook.com/WarhammerPioneerCentre/
Shop 233-234, 2nd Floor, Pioneer Shopping Centre, 750 Nathan Rd, Mong Kok, Kowloon, Hong Kong
It has 4 tables: 2 for demo games of
40k/
AoS respectively, 2 for painting (for 4 painters comfortably).

For actual standard-sized gaming tables, there's still Fun Atelier on the Island side:
https://www.facebook.com/FunAtelierHK/
2nd Floor, Bayfield Building, 99 Hennessy Road, Wan Chai, Hong Kong
It's a larger store, more convenient in case you're on the Island, but is not
GW-exclusive.
