Malaysia has okay portions. Of course, compared to places like the US, what Malaysians eat would be considered very little. Some restaurants/stalls are run by stingy people who just want to make money, so the portions can get small.
For example, here's what you would get when you order just a 1/4 chicken from Nando's.

How large are portions in your region?
For me, I just want to eat a bento made by Asahina-san. The portion doesn't matter one bit.
