If you like Asian food (i.e. spicy) then I'm told that the Y AVML beats the Y VLML. However I can't stand spicy food and so on the 2 flights when I ended up with an AVML I swapped with a companion and avoided the meat bits of their meal.
On previous NCW flights I have requested the VLML and I have been presented with the veggie option off the main menu, the bonus being I got served first.
