brilliant airport changi - easy done
have also found a much better shopping set up at the airport than some of the unsaviouries in town.
Food wise I would have no issues with eating anywhere in SIN, its very heavily regulated by the government.
The hygiene is !
I have issues eating at a number of places ... nothing to do with food hygiene, all to do with quality (only after visiting lots or living here do you understand why people queue 30mins for chicken rice at one stall and the stall selling chicken rice 20m away has no-one waiting).
