Sorry but your Granny’s Sunday roast does not get exported all over the world. One of the most diverse countries in the world with influences from all over that continues to innovate, you can bet the food is good.
For someone living in Taiwan, I’d get why they think American food is all fried crap and fast food. But I just came from there, even my Taiwanese SO complains that the food and quality here pales in comparison. We have access to farm-to-table fresh ingredients, Sunday brunches of eggs benedict with prosciutto, french toast with apple cinnamon butter and apricot marmalade, cajun crawfish boils, slow cooked pork green chile, breakfast burritos the list goes on and on. Whereas here the best I can hope for in Taiwan is a decent burger or pizza. I never even ate burgers back in the states.
If you think American food culture is all mcdonald’s and budweiser, then you’re living in the 1970s. The most popular trends in food, beer, drink are by-and-large being exported from the United States more than anywhere else whether you’ll admit that or not.
