Pretty good for a lunch special. The portions were big -- the sushi was more like sashimi wrapped with a teaspoon of rice -- and it came with pretty good miso soup and a small salad. Points deducted for an iced tea that obviously came right out of the can.
I wouldn't say that I'd run back immediately upon returning to Toronto, but staying at the Courtyard across the street, Koyko gets points for convenience. Seemed like it would be nicer to eat outdoors as it was sort of dark inside (and not in a good way).
