Went here a couple of weeks ago while kicking it in Vegas. The restaurant is located in the swanky new mall next to the Aria. The ambiance is really cool and the staff was extremely knowledgeable and helpful, especially with recommendations. We went on a Thursday night so it wasn't all that crowded and the food came out relatively quick. Here's what we ordered:
Sesame Kelp Salad - Good, but nothing special. Not that different from seaweed salads elsewhere.
Yellowtail Sashimi - This was by far the best dish we had that night. Flavorful and delicate with a nice citrus/soy kick. The fish was the perfect temperature and it all just melded together brilliantly.
Seared Albacore Roll - Very good as well. Great blend of flavors but similar to other really good rolls out there.
Soft Shell Crab Roll - I really liked this one because of the extra crunchiness of the crab. Maybe they overcooked it slightly because there was also a smokey flavor to the crab, which was really nice. The contrast of textures really played well together.
Order of Tuna Nigiri - Quality tuna and very tasty.
Order of Shrimp Nigiri - Pretty standard but still good.
Not too much food but still really satisfying meal. I would've given the place 3 stars but the yellowtail sashimi and killer ambiance pushed up to 4. Definitely a great date place if you have extra cash to burn because it's not cheap, but well worth the experience!
