Chinese Restaurants in Mexico City

Went to a chinese restaurant on Torres Adalid street in the Del Valle district. 4 big tables (10-12 persons) were already taken when my friend and I got in. the dishes are not cheap. They run around 78 to 100 pesos. Kind of like those in the bay area if not more expensive. It is not supposed to be an up-scale restaurant. And it is not.
I saw a lot of Chinese there. You can tell by their look and their accent that they are from the mainland. I have a feeling that 3 out of 4 tables of people were from Huawei. They just finished working on Saturday and were having a meal there. The manager-like men were talking loudly, with a lit cigarette on their mouth, shirt un-buttoned, running around asking people to eat, drink, asking the owner to get more rice or tea. People were walking past the Mexican waiters to their napkins, plates, chopstickes, etc...
Suddenly, I felt like I was back in China again. and I really don't like the Chinese people, especially when they are in a group... My Mexico co-worker's boyfriend works for Huawei, Mexico and he was bad-mouthing Huawei. Big time. I said to him that I could not agree more.
But the food is good. At least more authentic than those in the Chinatown in downtown, Mexico City. definitely much, much more expensive than the Mexican food here...
Still no Taiwanese here. I am such a loner...
