My favorite place for takeout sushi in the pedway. The pre-packaged maki is surprisingly flavorful, and checkout is swift - there's never much of a line. It's nothing fancy, but it is an extremely efficient lunch if you want to sate your sushi cravings and get back to the office quickly. Plus, the guy behind the counter gives out free samples of the special each day.
That said, I can't vouch for any of the non-sushi dishes. The spicy tofu soup I got here once was so greasy and tasteless, I threw most of it out. That didn't spoil my opinion of the place, though - the rolls were what kept me coming back anyway.
