Hands down, best sushi in Boston and the best value as well! Once you get over the fact that you enter through the Dunkin Donuts or the Deli, you'll see Osaka is a true hidden gem! Again, the sushi is top notch and the service is excellent. The spirited chatter between wife running the floor and husband behind the sushi bar is a spectacle in and of itself. Do take time and wander away from your sushi favorites and try some of the wonderful Korean dishes available as well.
