Great Japanese restuarant, and I believe they deliver anywhere in Madison! I live at least 5 miles away (NorthSide!), and they deliver in 45 minutes on a large order of food!
As far as the food goes, it is high quality. My favorites include the spicy tuna roll, the Dragon roll, and the Ikura (salmon roe). Probably the best sushi/sashimi value in Madison.
I've only eaten in the restaurant once, but it has beautiful woodwork, a fancy sidebar and sushibar, and excellent service.
