Nostos is one of the best reasonably priced restaurants I have experienced in the Northern Virginia suburbs. I have eaten there several times during the past two years and been impressed each time. The decor is modern and upscale but soft and comforting. The tables are spaced far enough apart so that you don't hear the people next to you (unless it is a loud group, which happened during my last visit). The overall noise level had improved on my last visit because the management had added soundproofing to the ceiling. The servers were efficient, friendly, and helpful even though the restaurant was nearly full; the wait for the food was appropriate given that dishes were prepared fresh. Fantastic Greek food. The entrees ranged from standard to unusual, and were attractively presented. They had a good wine list, too. The restaurant is tucked away in a small, unimposing office building, so map it out before you go or you may have difficulty finding it. There is plenty of parking. I recommend Nostos highly. It's a special place amongst a sea of fast food and franchise restaurants on and near Route 7.
