Sorry to reply you so late ! The couple is priced at $300 (90 days) and $500 (180 days). 50% off on food & beverages and 15% off on alcohol & set meals.
BTW would you consider another place instead of this ? e.g. the cafe at HK park ? No child-proof playground like RT but lots of exciting places in the park, children playround. And it would be close to MTR station and Pacific Place. Just a suggestion for a change :)
