All good suggestions!
Brandi and I are what you might call sushi snobs

and while nobu and tao have incredible atmospheres our vote would be Sushi Roku at Caesars Palace
Best Sushi in Vegas

Went to Roku for the first time on Friday. We go to the one in Santa Monica usually. Very similar to Nobu at the Hard Rock but with an amazing view of the strip from our table. The sashimi was as fresh as in LA and the staff was nice and high energy. Great spot for Las Vegas.
Pros: View, Fresh
Overall user rating: Highly Recommended

Hidden Gem
Posted by ferbs12 on 09/27/2005
This hidden Gem in the corner of the third floor at the Caesar's Forum shops is incredible. Go for dinner or even better make it over there for happy hour where you'll receive unheard of deals on sushi and drinks at the bar. Try and make it Wednesday through Friday evenings when Ryan is behind the bar. His Texan hospitality and overall knowledge of the menu and drinks he pours makes you feel extremely comforatable. The restaurant is clean and well designed without being pretentious or stuffy. If you are in Vegas make it a point to check this place out.
