The only fast food I enjoyed in recent memory was Pizza Hut. During some scare about MSG they removed all of the MSG and I ordered it a time or two after that and it was nearly inedible.

I suspect similar things happened with other types of fast food. I think there’s a flanderization effect happening with a lot of it. The same is definitively not the case for things like pizza in general, as I can order from my local NY-style pizza place and pizza is still just as good as it ever was.

It wouldn’t surprise me if fast food was objectively shittier across a number of different metrics.
