On previous visits we really enjoyed the food, but evidently the smell was masked by kitchen activity. The smell was actually so bad that it seemed to linger in my memory for days afterward.
When we mentioned the smell to the sushi chef, who is probably the owner, he just stared at us. He's never been friendly, but he seemed almost hostile.
Also, the turnover in wait staff is constant, so it's the luck of the draw, but it's never been very good.
We were once regulars, but after the odor experience, we will never go back. I honestly think they will have to burn the place down to get rid of that smell. The staff at the pub next door were very familiar with the problem, also.
