My wife and I recently dined at Mizumi, while on a short stay at the Wynn, and I'd like to share the experience. The ambiance, while understandably over the top (this is Las Vegas after all), was duly charming, with a large waterfall serving as an impressive backdrop to the dining experience. \n\nWe started with an expensive Toro tartar, topped with a very small amount of osetra caviar and edible gold leaf (pretty!) which was well presented, and generally enjoyable, although at $45 I would not order it again. We then ordered an assortment of sushi, including yellowfin tuna, mackerel, albacore and so on, and that's where things went wrong. At best, the fish, while reasonably well cut, was a touch \""dry\"" and certainly less than impressive.The flavors were somewhat subdued, and the preparation below what should be a relatively high standard, given the prices. In some cases, the use of Wasabi seemed excessive, hindering rather than enhancing. The rice itself was adequate, but nothing more. \n\nThe service, in all fairness, was courteous and professional. We were seated promptly and treated well throughout. Had the sushi risen above mere mediocrity, my review would have been far more positive, but it did not. Please note that it is only the sushi that shaped my opinion. Perhaps other dishes fair better.
