Sweet and sour pork with black vinegar sauce at a Chinese resutaurant "Fukui-Gen"

Although it feels much cooler than a few weeks ago, the temperature during the daytime often rises around 30 degrees Celsius. Obviously it's still summer. I feel like eating this sweet and sour pork with black vinegar sauce for lunch even when it's hot and I have no appetite.

Unlike ordinary sweet and sour pork, the ingredient is only pork. The restaurant seems to be run by a Chinese family. Honestly, I am not sure whether it is Sichuan or Beijing style. But anyway, I like the taste and always eat it from their dozen of set meal menus.

The restaurant is always busy and smoking is allowing at lunchtime as well, so sometimes smoke comes from tables close by. This is the only problem for me but I have to accept it, so I try to think that I had some bad luck on such a day and have a patience with it. But even thinking of it, I like the unpretentious atmosphere, the inexpensive and delicious dishes of the restaurant.
