"He's shown us that the food we all love to eat on the bench or around the barbecue can be cooked so well that it's great to eat in a restaurant too."
The Depot website tells of Brown's attitude towards food: "In season, beautifully cooked, to be enjoyed with friends."
It says most of the food served at the restaurant is cooked over charcoal or hard wood, making for more succulent and flavourful dishes.
Wilson said many Kiwi restaurants were starting to take a more "casual" and relaxed approach to fine dining, but Depot was leading the way.
"Lots of chefs say they do this kind of thing. But no one understands it or does it as well as Depot - the simplicity of it is often the best part."
Other winners included The French Cafe (best service and best drinks list), Cocoro (best Asian), Toto (best Italian) and Michael Meredith (best chef).
