If you're a fan of local food, it's worth checking out the Savour Ottawa website. This is not a review site, but lists Savour Ottawa member restaurants, who must purchase certain percentages (depending on the level of membership) of local food (designated as Ottawa, Gatineau and adjascent counties). Members (both farmers and restaurants) are inspected to ensure they're not cheating in what they claim is a local product.
