My wife and I did lunch at Roku last month and I wasn't blown away. Nothing bad, just average/good. Maybe my expectations were too high, or maybe they had an off day.

In the Caesars world, I much prefer Hyakumi, which is by Cleopatra's Barge. Not sure if it is the food, location/ambiance, or the rowdy attitude of the Chefs that makes it better, but I like Hyakumi more.

I think Okada (at the Wynn) is the best sushi town.
