Where to buy a roasted duck? - 新加坡

Last time I went to visit a friend in Bukit Gombak and bought a
roasted duck for S$35 there. I was surprised to learn that the duck
was so expensive in S'pore while everything else is reasonably cheap.
Then I was told that I did not buy the roasted duck at the right place.
An auntie I met in the food court (we just happened to sit at the same
table because it was crowded) told me that there is a famous roasted
duck booth (also with BBQ pork) in Jurong East (Blk 5XX I did not
remember...maybe 3XX or 4XX) where I could take #198 to. The price will
be around S$15 or so. I did not take a note so now I do not remember
where it is...and I want to buy a roasted duck tomorrow...

so I am now trying my luck here. Does anyone know? or you could please
recommend another good place to go? Thanks for your help.
