This is a great place for taking out of town visitors because you have to wander around Hou Hai (usually as the sun is setting) and then make your way back through the hutongs to find this hidden gem.
The food is fantastic, I love Yunnan food in general, so to find this place has been a pleasure. The prices aren't cheap, however for 2 people you'll spend about RMB150 - 200 if you order a few dishes and alcohol. Try the eggplant, crispy potato triangles, the lettuce wraps and the fried cheese. The skewers are very good as well.
The atmosphere also adds to the quality of the meal; the rooftop is lovely and perfect for summer dining. I love the trees and plants all over, it is colorful and cool and feels authentic in a touristy way (and I can only say that since I have yet to visit Yunnan Province).
It is a great choice for yummy food and a cool atmosphere.
