Stayed at the XV hotel down the block and sat at an outside table. Nice selection of rolls and very good service.
i would recommend going to Zen if you're looking for a good sushi roll.
Only constructive criticism is that I wish the rolls were a bit bigger - in comparison to other sushi places I've been to, they were a bit smaller than usual. I ordered three different rolls and inhaled it fairly quickly, then looking for more! 8-)
All in all, a nice place for a roll - and sit out front on the sidewalk if the weather is nice.
