In Singapore, my favourite takeout is very simple: Hainanese chicken rice. Lots of chilli sauce but white meat only and no skin or bone. A side order of dumpling soup goes down well.
In Australia, my favourite takeout is chicken nasi goreng from a ship called Noodleland. It is actually better than any of the nasi goreng I have eaten in Singapore, Malaysia or Indonesia thanks, I think, to the chilli oil that it is cooked in. It's the only food I miss when I'm in Singapore (aside from the outstanding Szechuan chilli chicken and hot and sour soup that my local Chinese restaurant serves... but I can get both of those here).
