Updating this review yet again after many more visits...this place has honestly become my favorite restaurant in Madison, right up there with Heritage Tavern and Graze.
Red has fantastic quality sushi compared to any other Japanese restaurant in Madison. Muramoto honestly does not come close - I really can't understand people who compare the two. Red blows Muramoto out of the water.
While it is a little pricey, the quality and surprisingly large amount of sushi you get (the more expensive rolls are quite bulky) compensate for this.
One standout roll I've been obsessed with is the Butterfly Roll - perfectly seared albacore and the mango salsa adds so much interesting flavor. Highly recommended!
Please do yourself a favor and come here. I can't emphasize enough how much I appreciate having a place like this in Madison!
