Yama Restaurant in Vienna is located on Rt 123, 328 Maple Ave W, Vienna, Virginia in a little strip mall. (Be careful not to go to Maple Ave East – you want Maple Ave West – still on Rt 123 – located next too the Dunkin Donnuts)
It is a small Japanese restaurant that is about 10 to 15 minutes from Tysons, however worth it if you want good sushi. The atmosphere is blond wood furniture and a small sushi bar and a few small tables. Service is fast and friendly though.
The sushi is fresh, priced fair and the rice is fresh and they don’t over-use it. They do offer specials and offer toro as well. They have a nice sake choice too. For Vienna this restaurant is a hidden gem. You go because the food is just…. good. Plain and simple.

Took a drive to this restaurant today and it was no longer there! It’s now a pet grooming salon of some sort. Shame…
