I've been going here for years, and I Sushi is my favorite! I've lived in Vegas for decades and have been to plenty of other sushi restaurants in town.
The service has always been great, and I've never had a bad meal. My favorite rolls are Ryan's Roll and the Monkey Roll.
Yes, their prices are a bit high, but I feel it's worth it.
I was actually quite surprised by some of the negative reviews. But, I guess you can't please everybody all of the time.
