Restaurants and culture

Do you ever notice when going to some ethnic restaurants that it is Americanized? Notice that the portions are large and the ingredients are different. I have noticed this especially with Chinese restaurants; the food is not authentic Chinese, it is American Chinese. This means that it is sweeter rather than the bland acidic flavor of truly authentic Chinese food, at least as I have experienced it. That is why they add things like hot sauce to their food to make it really spicy. Of course perhaps I should ask my bro for more accurate information.
