there are certain items that are only available in the MDR on certain days (Eggs Benedict for one). Here you can get it every day. Also they seem to be very open to special requests (add this, remove that). But I agree that the personalized service is really the main selling point. After a couple of days they know what kind of cold and hot drinks you want, if you always want a plate of fresh fruit, etc. One time I asked about almond croissants as there weren't any on the pastry tray. EVERY day after that they had them for me even if I wasn't in the mood for it!
