I love the service and attention. Sushi quality is good not great. We've been a couple of times, here are my suggestions they need in order to gain a loyal following.
1. The all you can eat option has far too many restrictions, just raise the price and limit the restrictions to a few things. Or put those on a separate page of the menu.
2. Stop threatening to charge for uneaten portions under the all you can eat. Portions are so small I doubt it's a cost issue.
3. Delivery of food items gets very slow after the initial order, if that's intentional then stop it. It's very noticeable.
4. Portion sizes of just about everything are the smallest I've seen in any sushi restaurant in Las Vegas.
