I went to Kushi this week with my friends Jon and Jocelyn.
The three of us were impressed - the food was good and served promptly, the prices were reasonable and we liked the atmosphere.
In particular, we enjoyed the very enthusiastic "hello" in Japanese that the serving staff screamed everytime that a new customer walked in. At first, it took a little getting used to, but now I would not rather eat Japanese food any other way.
