Nostos (Vienna, VA)
Lest one think from the previous reviews that the Tysons Corner area is entirely mall-related dining, rest assured, there are a few gems hiding in among the malls and box stores. Nestled a few blocks away from Tysons Corner Center in the first floor of an office building is the surprisingly pleasant Nostos, an upscale Greek restaurant. Since I had a free evening, this was also a good opportunity to get together with some of my DC area friends from TCF, so a group of 8 of us descended up Nostos.
