I have been in the Macau saunas, although my information is 10 years old. They would have AYCE, but very limited selection and the buffet was not open all day only certain times of the day. You could also get unlimited beer, soft drinks and tea all day, not just during meal times.
They also had a sleeping room which I took advantage of, not wanting to take the ferry back at 3 AM.
I returned after many trips, with all organs present.
I suspect things have not changed significantly since this time.
Keep on mongering
