@Elegiaque - sorry, was away and did not have the bandwidth to reply to this. If there is one person I trust when it comes to *good food* in HK, it is @goodfood and his recommendations. He's been a long time friend personally and of GeoExpat and if he says it will be good, I trust him...
@Natfixit, as goodfood mentioned, would be a logistical nightmare -- the whole restaurant has been booked (they're pulling an extra shift I guess on Sunday afternoon for this event) and it is pretty much all in or not. Sorry!
