Great customer service! Really good tasting rolls for a Buffett set up. Fairly easy to get a table, service, and food within minutes at peak lunch hour even while having tons of people during a weekday. I don't think my water was ever empty. I took one star off because even though it's a buffet I have seen cleaner/better sushi buffet set ups (they just didn't have the flavor Ru San does), so they could turn the more picky people away this way. Still just as yummy as locals rave about.
