On to the good part, the sushi! It's actually quite enjoyable, especially for a buffet. Nigiri comes in small portions, smaller than normal nigiri sushi you get at any sushi place. So you can get a variety without stuffing yourself. Also, there's a decent variety to choose from. And it's always nice to get some seaweed salad to go along with some good sushi.
Next good thing, the hibachi grill. You get to pick up the items you want to be grilled, put them on a plate, hand it over to the hibachi chef. About 5 minutes later, you get a steamy hot plate of hibachi grilled food. You can choose a combination of meat: chicken, beef, shrimp, and scallops. You can also add noodles and a variety of vegetables to your plate. It's fun just seeing the chef cook your food right in front of you. There is a line for it though. But overall, this place rocks.
