I think in the past some scientists without credible proof spread rumours about MSG being bad for health so many people especially parents don't let their children consume such food. Health conscious people are not gonna touch this but this claim was debunked later and in normal amount it's pretty good but lots of people still avoid it like plague so some hotels don't add it. You guys add it in everything there right? That's what my Filipino friend told me. I was quite surprised to hear that.
