Keifa/Seijo
桂花/成城
Excellent Chinese dishes, including a good peppery sour suratanmen. Excellent volume and good balance of noodles, mushrooms, pork and egg. Semi-hidden on the second floor of the building next to and north of Odakyu Seijogakuenmae Station. Waitstaff very friendly, interior a bit old but excellent reviews on Livedoor.
