I will be visitting SGP in 2 weeks for 3 days on my way to Jakarta. I was born in JKT so I know the food scene there. But in SGP, I have few clues for the UNIQUE dishes. Maybe someone who have been there a while might give some pointers.
I heard that the chinese dishes there are unique and superb.
So far I got:
-Hainam chicken rice
I do not care for ambiance - food is more important. Great quality at lower prices is even better. For example, in JKT you can get good satays at a 5 star hotel for like $10 but if you know the food scene, you can get same quality or better satays for like $0.50 at a clean stall on the side of the road.
