MSG is naturally occurring in things like seaweed, tomatoes, mushrooms, and Parmesan cheese.

It tastes fine given the popularity of those food items.

I quite like the taste, it has a mild but distinctive flavor but it's much better in the background and it can be overpowering if it's the main flavor, which was my complaint with KFC. Kinda similar to salt, a bit of salt makes everything else taste better but too much overwhelms.

MSG is neither terribly dangerous nor perfectly fine: https://www.youtube.com/watch?v=E-POAKKH5IM

An interesting commentary on both of the above questions.

The issue in the context is MSG tastes like what “mono-sodium glutamate” would taste like.

The video about both about what MSG tastes like, and it's safety... hence I posted the link.
