Spoon and Fork is among, if not the most reliable AYCE sushi spots in Oakville. They have a number of locations which isn't a coincidence, they are consistent in their quality and service.
The fish is very good, and the bar is stocked with several beers and other spirits. In terms of the menu, they could stand to add a little more-- their Plus locations offer a much wider variety of sushi and other foods. However, there is enough here to have a nice meal. It is pricey on weekends and at dinner so aim for lunch.
