Oh upon check in I was given not only a free drink certificate but another certificate for 135 HKD food and beverage credit. They said it was good for any food and beverage on the property, including room service, but excluding minibar.

So they're offering $17 USD to try to get you into a restaurant or to call room service, where you'll almost certainly end up spending much more.

I might use it tomorrow to order ala carte bacon and eggs for breakfast, the certificate should just about cover it.
