I tried Sono Sushi about a week ago with a friend and really enjoyed it so last night I decided to give it another try. I wasn't disappointed. Started with a mixed assortment of sashimi and left the selection up to Tom, the head chef. There were five different types of fish, each one very fresh and well sliced. I followed the sashimi with an order of the Age Dashi Tofu which I also had on my first visit.
The highlight of the evening however was the Hamachi Kama which is listed on the appetizer section of the menu for $10.95. Hamachi Kama is one of my all time favorites and this one was the best version I have ever had in Boston. I don't know where their source is but this was a very large, thick serving, perfectly cooked, not overly salty and served with a nice ponzu dipping sauce. It was really large enough to share between two people. I will keep returning to Sono Sushi just for this dish alone.
The restaurant was very busy but the service was still very good and friendly. If it stays this way I'm sure they will do very well.
