not a potentially stupid question at all. Hawker stands are food courts serving some great food, an example thread here from the Singapore Forum: http://flyertalk.com/forum/showthread.php?t=308935

Some are open 24 hours, open air. A great place to get some chow and some beer.

Hmmmmmm, you are on the same flight as myself, you just might have to come with me on Friday night to a hawker stand and find out for yourself.
(I would be willing to believe others would be interested as well).
