I really love their hot and sour soup, I've never had anything like it elsewhere! They use high-quality fish for their sushi, so their nigiri and sashimi are tastier than other sushi places in Madison.
Two things prevent me from giving this restaurant five stars (and they are both just based on my personal preferences): I don't love their spicy tuna roll - it's a little too spicy for my taste (I prefer Wasabi's spicy tuna roll instead). I also wish they offered a sweet potato tempura roll (their veggie tempura roll is just carrots and asparagus).
If you are looking for quantity and quality - it's particularly worthwhile to go during the day for their lunch specials.
