I take issue with the common claim that 'curry' isn't a thing in a 'real' Indian restaurant. I did a quick survey online and could not find a single solitary Indian restaurant menu without curry on it. From the fanciest to the common takeout joint. There are even chains like 'Curry House'.
Let's tone down the virtue signaling in food reviews. It's silly. There are 150 languages in India; there are as many cuisines. To claim knowledge about the 'real Indian' food or culture is transparent nonsense.
On another slant, it's a rampant issue in YouTube videos where anybody with an Italian accent claim only they know how to make real Italian food. Learn a little history, folks.
