Yes, that's a great facility offered by SQ.
The more I hear of the catering "innovations" being offered by other carriers, the more I feel that Emirates (overall still a very good carrier) are now behind the curve rather than ahead, where onboard food is concerned. On a number of recent EK flights I have been struck by the fairly limited range - and, more to the point, a certain lack of imagination or novelty - in the F class menus.
