Ok thanks Mia, I did just that.... they advised do not have an online list anymore. When the agent asked was there a particular city and I mentioned Hong Kong, he did say he would email me in a little bit the complete list of restaurants in Hong Kong they work with.
I also asked, which I saw earlier in this thread if there are any perks to book through them (free prosecco I believe was mentioned), they advised only for certain places domestically where they have a relationship with.... there are no international establishments that provide perks through this service...
