This is our favorite sushi spot. It's small but it has a home town feel. My husbands favorite roll is Firefighter #4 but he also loves the Hugito Explosion! I love the Josh appetizer and now I started ordering off their "Green" menu, which is...More

This restaurant is fantastic, fish is fresh and chefs are very creative. We have never been disappointed. We love the infusion roll with jalepino and the Zach rolls. Fresh sashimi can't be beat. It's a really small restaurant, make reservations or go early.
