Agree with all of the above, which makes you wonder how they got that popular in the first place.

I would add to the list of fads that I wish would die out; designer gluten free products (and those that consume them for no clear medical reason), which I hope have peaked and are on a downward trajectory.

Had dinner in Munich last week with 3 otherwise sane old University friends and they have all developed an "intolerance" after functioning perfectly well for 30+ years. A german beer garden was, in retrospect, a bad choice of venue.

I think Bubble Tea has also had its day. Most of the places that have sprung up are dire + and it's one of those foodstuffs that just doesn't seem to work outside of its geographical context.
