Title says it all! This is one of the best Japanese food restaurants I've experienced. I've only been there once for a business dinner but the experience was wonderful. Right from the beginning I was welcomed by their friendly staff and chef's at the sushi bar. The atmosphere was spacious and warm. I requested if they had any table that was quite and a little bit private for my business meeting, and they provided me my own personal room! It was perfect. The food was authentic and very tasty; and for those that do not sushi they have a plentiful selection of non-sushi entree. My client had the teriyaki salmon and was told that I was very good.
The only thing that would make my meal even better was if they served alcohol. But I found out its a BYOB and there is a liquor store right next door. Very convenient.
Overall, if your close to millburn and you was something that is delicious with a nice and comfortalbe setting. I would hightly recommend Sono's.
