Osaka Sushi isn't easy to find, but it's worth the search. Regulars love this place with a fervor bordering on obsession and even have their own personal sake boxes, stacked like a child's blocks behind the bar. The menu focuses on sushi, but also features other Japanese convenience foods — gyoza and donburi, yaki soba and bowls of multi-colored fish eggs for those who just can't get enough tobiko and ikura. While on the surface, Osaka might seem no different from the dozens of neighborhood sushi bars in this town, its excellence reveals itself in small ways.
