I haven't read the reviews for Osaka House. I found it by simply searching out good Sushi on State Street. I've since been there many times and have never had a poor experience. It is small but when the weather permits, sitting outside on the sidewalk and watching the street life makes for an awesome experience.
Tao (the owner) is ever present and extremely attentive. He has always been very helpful in making suggestions on different rolls and I, nor my guests, have ever been disappointed.
The price for what you get is, in my opinion, a great value. I sent an out-of-towner and her guest there and they agreed, it was fantastic.
Tell Tao that Brian sent you and have a great experience!
