I occasionally debate about the best sushi place in the Madison area. Usually it comes down to either Red or Muramoto, but for my money, Muramoto is the winner.
Never had bad or even sub-par sushi here. It's always beyond delectable, and if you're not picky, you can get three excellent rolls for just 25 bucks with the "Chef's Choice" special.
My only complaint is how they gouge you on drinks. Buying a 25 oz. carafe of decent sake there is upwards of 40 dollars, while I can find the exact same stuff at Woodman's for about half the price. I get they need to make money off of it, but there's a limit.
