They’re shitty junk food with nostalgia. As other’s have said, try our Chinese food. And our Mexican food. Also hit up an American restaurant here, especially a diner. Oh and wherever you go ask the locals about their local food and try it, (it’s not weird, we do it when we travel domestically) you’ve probably heard of stuff like Chicago deep dish and Philly cheeses teams, bur basically every city has something they cook good or unique and are super proud of, like Cincinnati has a style of chili they put on spaghetti.

America’s best cuisine isn’t our mass produced mass market foods, its the stuff immigrants came up with to square their cuisine with the available foods and local tastes.
