Yoon is a small Ningbo-style bistro tucked into Changle Lu, serving a mix of seafood-focused dishes and homey small plates. The space is cozy and warmly decorated, with a glass ceiling that keeps it bright during the day and atmospheric at night, making it more suited for drinks and a casual catch-up than a full dinner. Standout dishes include the purple seaweed rice with marinated sweet shrimp, the red-miso crab, and the seasonal wormwood glutinous rice dumplings. Service is attentive, with the owner often checking in and offering drink recommendations. Portions are on the smaller side, prices moderate, and the crowd is mostly locals and friends meeting for a relaxed meal or drinks.
