Italian restaurant cuisine today is judged by whether it tastes like the way their particular Italian grandma made it.
Asian restaurant cuisine is judged by partly by how different (technique, taste, looks) the dish is from what they can make from home.
I don't know how relevant it is, but my wife and I like to eat out at places where the dish/cuisine is something that we simply cannot make at home. If it is too similar, my wife will sigh "we could have just made this at home".
Of course that situation may be reversed for people with a Chinese grandma instead of an Italian grandma.
