Onslow is a restaurant at the corner of Agra Crescent and Ganges Road in Khandallah, Wellington. It serves lunch and dinner, with à la carte dining, prix fixe menus and set menus for sharing and celebrations.
The menus follow the seasons and focus on New Zealand ingredients, so the food changes with what is in season. Its signature service is a salmon and martini trolley. The website describes it as a Krug Ambassade, with a Champagne list to match the food, and says it suits intimate gatherings, larger celebrations and corporate hosting.
