This restaurant is right across the street from my house so I'm a frequent visitor. I have to say that every time I go back the food and service just keeps getting better. The portions are generous compared to the price, and the waitstaff is extremely attentive. Now I've never been to Yunan so I can't comment on whether it's authentic Yunan food or not, but it definitely is very delicious.

The rice wine is definitely worth trying and my favorite of the restaurant.
