I just came back from my last visit in '15. Great atmosphere, our server Anthony was very knowledgeable about the restaurant. We got a table which incorporates an amazing view of the lake indoors (right behind the glass screen). There is outdoor seating right next to the waterfall but it's easy to forget you're in Las Vegas due to the atmosphere (which is certainly a compliment). I'm sure there's a perfect season to go out and (there's heaters if you're going in the Winter) but I didn't see any fans out for the Summer. Music choice was a bit interesting since it was Pop music from what I remember. Not sure what I expected for the atmosphere the restaurant gives off. Mizumi - or the Japanese spelling Misumi - means beautiful women in Japanese which is why Steve Wynn named it Mizumi.
The fish was fresh, and the sashimi list provides information about where various fishes come from. I found it interesting when I asked our server if the eggs in the sweet egg omelette actually came from Las Vegas & he said they did.
The kitchen doesn't have a preset way the items are brought out (example: Bringing out heavier hot dishes first and presenting lighter dishes at the end of the meal). The food comes out when it's ready. If that's your preference like mine then it's probably something to be brought up.
Our plates came out in this exact order:
Toro Tataki(ala carte from sushi platter) came out with the Foie Gras (hot plates). The toro tataki was great quality and a pricier dish but you definitely get a hefty amount for what you pay for. It's paired with taro chips (yes toro with taro chips lol). It was more of curiosity when ordering the Foie Gras. Chef David Hashimoto worked under Alex (French) restaurant before so he incorporated his french cullinary background in this dish. It's definitely not Japanese (lol) so if you're a foie gras lover like I am then I would recommend this dish. The Foie Gras ended being a mix of sweet, salty, and tart flavors.
Next came out couple orders of nigiri(light) which came out fresh next to the Scallop Tataki and Crispy Shrimp Roll (rich). The fish was great quality and I would recommend the roll for individuals who steer away from raw fish.
We were lastly presented with the pork belly from the robatayaki menu. It was delicious, extremely rich, and I would recommend it.
Didn't save room for dessert sadly. I recommend window seating if available.
