[Note] Personally, I've never been successful in making a reservation for this restaurant. It's become way too popular to do so as a first-timer customer. You must be very lucky for some reason or know someonw who could squeeze in there.
From what I've heard from those who have actually been there, combined with what has been said by so many reviewers, Saito should probaglby be ranked in top 5 for Sushi restaurants in Tokyo.
My rating: 5.0+ (Awesome!)
