My mistake, should have typed "full breakfast in the main restaurant" (Vivre). Reception on check in advise breakfast can be taken in the lounge or restaurant.
Interesting. We've never been offered breakfast in the restaurant in 15+ Platinum stays. That said, we've never paid for a room that includes lounge access (we usually book just classic or superior). Maybe your bookings are more lucrative for the hotel, or you're a very regular guest?
