I ate here on a Thursday night before the late Cirque show at the Mirage. The sushi is definitely pricey but tastes fresh. The duck was absolutely devine. The waitress was attentive although we did run out of water once. Our food came out reasonably quickly--it was actually good timing because the sushi came out first, which we were splitting, and just as we were finishing, the duck entree came out, which we were also splitting. When we told the waitress we were going to the Cirque show, she was quick about getting our tab settled out.
Pros: great food, fast service
Cons: very pricey, especially the sushi.
