I was on this short sector as a continuation from Singapore, a few months ago, and here is the menu.
Refreshment menu
To Nibble On...
Olive bread with smoked slmon and onions, grilled vegetables
Herb croissant with ham and cheese, side salad
There was only 8 of us upstairs on this trip. I did not eat as they had served a large breakfast just prior to landing in Zurich. The space bed provided a few more minutes of rest.
