That New York Post article is a hate-filled piece of garbage.
For example, it hates against these "polarizing rat-riddled street dining shacks" (quote is from the article).
I can guarantee you, i live in Vienna, we have these things all over the place. There's at least 5 of them on my way from where i live to university. There's never been any problems with them. In fact, they're delicious and typically much cheaper than sit-in restaurants. That's probably because they don't have to pay for expensive rooms. That makes the food much cheaper, it's typically around 5€ for a kebab (basically a sandwich) compared to 12€ for anything you get at a sit-in restaurant. I have gone to these street dining shacks every day for years and never had problems.
