We come here on Monday nights for 1/2 price sushi (starts at 4, not sure how late it runs). Somehow we always end up spending just as much as we would for regular priced. It's good and we order a ton.
We usually start with miso soup because I love it and you can't get it everywhere. It's good and I think it's $1 during happy hour!
All of the sushi we order is quality, but you should definitely try one of the pricier "deep fried" rolls. My favorites are the saga roll or delicious roll. They are still warm when they are served, but trust me, it's fantastic.
It seems like they have some trouble with staffing; they are always hiring someone and there isn't usually a warm greeting when you arrive. I let it slide because I really like the sushi chefs here.
