I really like this place as a lunch spot. It's a bit small and can fill up with customers pretty fast; however the service doesn't seem to suffer a bit. Last time I was there, the bar was full and all but one table was occupied, and the staff still constantly made sure to refill my water and check on my hot tea.
There were also enough sushi chefs working that I never had to wait more than 30 seconds for the next thing to come out on my AYCE order. I prefer mostly the nigiri and a few standard rolls so I can't comment on some of the speciality rolls they offer. I also think the lunch AYCE might be one of the cheapest in town at $17.95. I will definitely be back soon for lunch.
