In fact, whether it is "Qingdao prawn" or "Sanya high-priced food stall", although they are well-deserved "black shops", they can't knock over a boatload of people with one stick. I think almost all tourist cities have "sky-high food stalls". I remember traveling to Beijing with my parents more than ten years ago. At that time, two cages of pork buns were bought at an early stall near the railway station.
On the other hand, there are thousands of tourists, and only a few people have been slaughtered. At least I have traveled many times personally, but I have never been slaughtered. Generally speaking, there is no way to avoid the pit. As long as I remember these points, basically I won't step on the thunder.
1. Don't go to restaurants near railway stations and bus stations.
In most cases, because there are many floating people near railway stations and bus stations, restaurants there are basically open to foreigners, and they basically eat once and leave. Shops are also holding the mentality of "killing one is one" and don't consider staying repeat customers at all, so the prices there are generally particularly fake, and it is easy to fall into the pit when eating there.
2. Try to go to crowded shops.
No matter which city has a local "fly restaurant", the environment of those small shops may not be so much, the hygiene may not be very clean, but the reputation is very good. Every time I go to a restaurant, there are many people waiting in line, even in places where many locals like to eat. These small shops are often the most affordable and authentic. So you can consult local residents and listen to their suggestions.
3. look at the raiders.
Now there are many travel apps with very good travel notes, which are very detailed about accommodation and diet. When you are free, you can avoid stepping on thunder to the greatest extent. In addition, there are some food-related apps, such as comments, which are recommended by netizens and the popularity rankings of special foods in various cities. You can also refer to one or two.
