I've been here about 6 times and I've always been extremely pleased with the freshness of their fish. I only eat nigiri sushi, and every item on their menu has always been excellent. I'm always very pleased with their Uni, it has been excellent and fresh.
The sushi chefs at the bar are fun to be with, but not over the top with entertainment. I've been to other places where the sushi chefs try to put on a little show, but the fish was not as good as Sakana. This place is my favorite on this side of town.
