The interior of the restaurant is great -- dimly lit, tasteful decor (you'll hardly remember it was a Wendy's years ago).
The food is what you'd expect from an AYCE sushi joint. Pretty large menu and decent range of options (including fusion/Canadian-style rolls too for those who are into that sort of thing). The service is prompt and usually fairly accurate (you fill out a menu card with what you'd like for the table vs. dictating your order out loud).
Not the best, but great for lunch (the dinner/weekend costs are higher, not sure if it's worthwhile then).
