Modern Asian Dining Expands in Mosman with Onice Restaurant

Onice, a modern Asian restaurant in Mosman, is attracting attention for its fusion of Vietnamese, Thai and Japanese flavours paired with attentive service.



Background and Opening

Located at 161 Middle Head Road, Onice opened in February as a new addition to Mosman’s dining scene. Founded by Alex Nguyen, who previously worked as a flight attendant, the venue began as a daytime café before shifting to a full modern Asian menu in response to strong customer demand. 

Mr Nguyen prioritised a welcoming atmosphere, offering both lunch and dinner daily in a space designed with glowing wall lamps, padded banquettes, and timber furnishings.
