The only place I will buy sashimi grade raw fish from. I've never ordered food from here, but I've bought toro, uni and other types of raw fish many times. They are very patient if you want to ask about the types of fish. If you want a smaller piece than what they have pre-cut, they are usually accommodating enough to cut you a smaller piece. If you're buying the raw fish, they'll also ask if you want them to slice it into sashimi pieces for you. They have many different types of uni too, from Boston or Japan. I've been here to buy raw fish to make my own sushi at home and it's amazing.
Just remember that they only have toro on the weekends because there's not enough demand on the weekdays. You can also go next door to the Jtown grocery store to stock up on yummy Japanese snacks!
