That would be an interesting idea for a breakfast service (on QF, too). I don't know how many people in Australia would be into a typical European breakfast of cold cuts and warm pastries (croissants, danishes, bread), but with enough variety of pastries and if the typical pax chooses 2-4, some may warm up (pun intended) to the idea.
Guess the problem is getting the last picks and all the other pax have taken the nice pastries (e.g. the blueberry or custard danishes, leaving the plain rolls behind).
