Fun Sushi Place for a group - DC?
Tachibana in McLean was where I had a group of 10 for dinner on a Sat. night. Food was yummy, and a lot of it. They screened off a little area for us so we felt like we had a private room. Beware tho, you should make reservation early. I tried to go for lunch a few Sats ago, and the line was a mile long....
