We had a pretty good experience at Sushi Wa. I'm glad they stay open till 4. We came in around 2:30AM and were the only ones there. It was nice, but I hope they get busier during the late hours.
Our server was very nice and polite. She took our orders promptly and the sushi chef was very nice too, checking in on us.
We liked the salmon sashimi, I liked their ikura too. Their spider roll was one of the best ones we've tasted too.
The bikini and lava rolls were also ones that stuck out to us. They were pretty big portions.
For dessert we did strawberry mochi ice cream, pretty generic but good:-)
Would definitely come back for the ayce when I'm back in Vegas.
