Despite the name, does both Japanese and Thai food, and well.
Sushi is of decent quality- both the fish and the rice- and is comparatively reasonable.
Pad Thai didn't quite taste right, but has been the only thing on the menu that wasn't excellent. Entree servings are on the larger side and definitely reasonably priced.
Service is average, both in attentiveness and speed. Wait staff is impersonal but effective. Can have a line up at peak times (lunch and dinner on weekends) which can be problematic and make the space seem crowded - I don't know many people who enjoy being stood over and stared at while eating - without a proper place to wait. Otherwise, the space is comfortable and frequently noisy.
