Beruga, I just asked my Chinese teacher (who is a native Kunming person who seems to know everything about restaurants in the city) about Eluosi de fanguans here. She knew only of Yalishanda.

There is no such place in Kunming and if there was the borsch would be spicy and full of rice noodles. There is a Russian expat community on Hainan island, in the south part, and I had some of my best food ever at some of those places. They have Russian people making fried cod with chips (fries to us Yanks0 in the markets, with tartar sauce and malt vinegar! So if you go to Sanya you will be okay. But not here in noodleville.
