The sushi here is very good. Super fresh. Yes, it is expensive but you're in Vegas and you're at the Wynn. If you have a problem with spending money then you shouldn't come here to begin with.
We were a little late to our reservation, but the hostess gave us no hassle at all. Our waitress was very friendly and honest. (She advised against the $35/oz Kobe beef. Said it wasn't worth it.) The service was a little on the slow side, but as long as you have a full drink and good company, who cares? My husband wasn't that crazy about his wasabi sea bass. He thought it was too spicy, but he's also a very bland eater. I tried it and I thought it was good. The drinks were perfect. They have a great saki list, of course, and a sommelier who is a little uptight and very serious about giving good service. The restaurant has a view of the Tryst waterfall, which is beautiful. Request a table with a view.
