One major benefit of having lots of cultures in America is the variety of food available.
American food keeps evolving, depending on which people manage to cross the border.
My first taste of American food came years ago in a college cafeteria and, as you can imagine, I wasn't overly impressed. Just overly depressed. Food in most college cafeterias is made to taste like it was microwaved and then sent through the dishwasher. Colleges serve unappetizing food on purpose, so students will have extra motivation to graduate quickly. The food at my college seemed especially bland to me, because I was used to the spicy food of my native country, India, where many people are guilty of murder, having killed most of their taste buds.
