This particular location is a major disappointment. I work nearby so I've given it several chances, as I love Japanese and have had good experiences at the Bell road location.
I've been here 6 or 7 times and have had worse than poor service each visit. I've never had a drink refilled, I've never received my food in less than 35 minutes, and I've never had anything other than marginal sushi. I have many friends that have given this location a go as well and they all had the same experience.
There's not much else to say. If you're thinking of eating here, give it a pass and hit up the original Bell road location. The last time I was there the service and food were both great.
