Doesn't get enough credit.
One sushi chef here came from the long-time sushi place Matuba in S Arlington. For the price, the sushi here is fresh and fast. Service is very good. They have a daily specials board highlighting new, different, and hard to find types of fish and other delights. You don't have to spend a small fortune (as at many trendy DC places) to have good food. The place is small, but intimate & nicely decorated. In good weather there are outside tables, though Broad St (aka Rt 7) can be busy during rush hours. Enjoy!
