The quality of food is probably extremely variable across schools even in the same general region. I’ve seen some pictures of really appealing lunches plucked from European schools. But how many different schools are there in Europe?
Absolutely. I work at a school where the food is OK, but just, and the school across the street has very good food. One of our students used to sneak into the other school in the mornings for breakfast. He made the mistake of bringing the food back to our school where people asked questions, and pretty soon the other school knew he wasn't their student and banned him.
Something seems really off to me about different kids within a couple hundred feet of each other getting drastically different quality of food.
I'm guessing a bigger consideration is whether what appears online is subject to selection bias (especially when the context is "look how much better the food in European schools is").
Maybe it's also changed a lot. My anecdata is admittedly not recent since I am also "not recent."
