What shady things do you know about food and dining?
There are some restaurants, in the frying time some dishes are not cleaned at all, and some meat, especially fat sausage and so on. Not much cleaning at all, directly with used for cooking. There are some bun filling, dumpling filling. Inside the meat, I do not know what meat. Even if it is good meat will not be cleaned, directly made into filling. Some of the food with filling, their own employees do not eat!
