haha no, I doubt those restaurants are changing their recipes because “people are watching cooking channels”
they want to be able to serve more people so they serve less opinionated food, if you serve something some people think is absolutely vile and disgusting but others think is really good you’ll get less business than if you serve food everyone thinks is just “okay”.
Even though we give the French a lot of shit, they stay true to their recipes for the people who like it. It’s very opinionated, if u arrive at a French restaurant in France and you don’t like their food, if it’s rather rural they won’t have an all inclusive “oh here you go” meal, you’ll eat the pig intestine or go hungry.
Less appealing to the masses, staying true to their recipes
I wonder if there's an element of cost cutting involved here, too. Restaurant owners have to juggle the availability and pricing of their ingredients. I know of at least a few cases when a menu change was done to get better ingredient reuse or to manage these costs.
