Deceitful? I don't think it deceitful mentioning that it is possible!
Most I ever paid for one dish in Singapore was $7 for fish head claypot. That's a BIG meal, designed for 2 or more (yeah, I ate the eyeballs!).
You can live VERY cheaply food wise in Singapore if you want to. Buy Western, and pay through the nose!
And not expat either - local terms (what a fool eh? Still living comfortably)
