When it comes down to the food and service, this place is definitely a solid 4 stars at LEAST. I thoroughly enjoyed the sushi - got an Alaskan roll and spicy salmon roll and both were better than what I would expect to find in Madison! The prices were great for the quality of sushi, in my opinion.
The ambience could definitely use some work - the restaurant is spacious but I've never seen it more than half filled, so I'm worried about their business...the decor is pretty standard and their round tables are much more suited for Chinese family-style dishes. Nothing jumps out in this department, but again, the quality of food and service more than make up for this.
I think this restaurant has great potential, given that it's only been open for a few weeks! I wouldn't expect the decor and ambience to blow me away or anything, but the food and service was certainly impressive.
I hope more people check this place out and enjoy it cause I think it's definitely better than most other competitors in the area (i.e. Wasabi). Give it a try even if it's empty!
