I have been to the Pearl in Scottsdale and it is worlds better than this one.
I have been to this location several times since it is nearby my house. I have been sat at a booth near a window and watched ants and other small bugs crawling on the inside of the window, right next to me. I've been sat at dirty tables. The service is hit or miss.. sometimes you get an attentive server and sometimes you get a server who takes forever to refill your sake or bring you your check.. which is odd because the place is stupidly small.
My boyfriend took me here in April for my birthday. Again, the service was meh.. took awhile to get our check and our beers. The sushi was very good, however a few hours later it didn't seem to agree with me. I have NEVER been sick off of sushi and I have eaten it for years from all different places. Raw tuna is one of my favorite things in the world.
I had the worst vomity, poopy experience ever after eating that.. thinking maybe it was something else I ate, it couldn't have been the sushi, the next day my boyfriend informed me of his gastric discomforts too. We were both sick for a full two days.
Save your gas money and drive to the Pearl in Scottsdale. Avoid this place unless you enjoy curling around your toilet :)
