hawker? if weather not hot lor........... 
actually quite do-able since it's not too much a burden on
everyone's wallets... but which hawker? u ask me i tell u bedok blk
85, even then i have no idea how to get there by bus lor....

but also cos of the temperature.. usually very hard to sit ard and
chat for long leh.... dinner time alot of ppl will "surround" you,
place too hot, may not have enuff seats if group is big....
