“A little over 15 years ago Olive Garden changed their recipes and that was a bad idea.”
I don’t recall there ever being a substantial change in the menu. It’s almost always (at least to me) been pretty much the same menu - albeit with occasional new offerings.
What was the old menu like?
I used to eat their frequently, and get carry out often. As an example, their Alfredo sauce was very well made prior to the wholesale change to their recipes, but afterwords was not even a close facsimile to their previous product. I used to order just their Alfredo sauce for takeout and make my own dishes with it. After the change, I won't bother as the product has been inferior ever since.
They ruined their Manicotti. It's nowhere near as good as they used to make it. Most of my favorite dishes were “ruined” when this change took place as far as I'm concerned, and I almost never eat there anymore, and when I do, I'm always disappointed as I remember when their food used to be so much better.
