If you've heard a lot of great things about this place, I can confirm Saku serves some pretty bomb sushi for the price you're paying.
We went on a busy night (New Year's Eye), and they did not have enough chairs for our table. One of the server (or Manager), went back home in the cold and rainy weather to bring extra chairs back to the restuarant to ensure all our party guests were properly seated, and not sitting on the floor. This was too-notch customer service I rarely experience, and our tip reflected that.
If you're looking for a great sushi spot that won't leave a hole in your wallet, this place is definitely worth checking out. For the Instagrammers, be prepared to work with the restaurant's warm and intimately lit ambiance.
