I have tasted Hunan dishes while I was in Beijing years ago. One dish that I like so much that I bet you will also sweating while eating is the green chili steamed fish. It supposed to be fish head but they have sold off and replace with an actual fish. Everything is ok except the taste of overall dishes are more salty and oily as it is Hunan style.
The restaurant is located at Uptown Damansara. Price is reasonable with the fish only RM 29. But be warned, good food will need lot of exercise after that. But worth trying.
