Coffee Seibu Nishi-Shinjuku is a 1980s-style Japanese vintage cafe in Nishi-Shinjuku, Shinjuku, serving omurice and Napolitan. The parfait is good and the coffee is clean, and the space has the feel of a classic Japanese cafe. It is an open space where you can rest quietly, and the food is average. The service is a problem: Korean customers are made to wait while Japanese customers behind them are seated first.
