Actually, it depends on your own taste. There are many Hunan restaurants in Shanghai, but there are too many flavors. If you want to eat, you can buy ready-made food online, all packaged. You can buy it back and put it in the refrigerator. The dish is half cooked, so you can eat it as long as you turn it on and heat it. I used to get some in Congchu, which is quite good. Now I'm just greedy and go online to get ready-made ones.
