Because what you see that we call mold is the fruit of a vast root system. In hard cheese if you can cut an inch or two in every direction from the mold you likely will get the root system with it. With a soft cheese (or bread) that root system is likely spread through the food pretty thoroughly.
Ok yeah what you are complaining about is valid but I can’t get over the $22.50 for Kids Shells… Like a fucking a pasta serving for children?! This restaurant seems insane to begin with.
Edit: Realizing it looks like prices are a line off but still $16 for kids food?
