The S$ is doing pretty well against the ¥. I don't think a
trip here is going to be that expensive for you guys, given the
advantageous exchange rate.
As for food, I discovered after my first trip here a number of
years back that the best restaurants are found by simply following
where the salarymen and office ladies go for their meals. You get
the more local flavor of the food at usually lower prices than if
you were to eat in the touristy areas.
I'm ok with back alley food and over-the-drain hawkers~ 
Infact I do that when I go Msia
Hmmm, it's not the price, or rather, it's the sheer amount
of food that chalks up the price
