DaDongHai is a haven for Russians escaping their brutal winter, so it's no surprise to find a great Russian restaurant in Sanya.
There's very solid Russian food and authentic vodka. Fried dumplings, borscht, and chicken soup with meatballs are all highly recommended. The seafood salad with pineapple has mixed reviews—some people love it, some people are deeply confused by it.
At dinner time, a man will come out and sing songs. Do not be alarmed.
