I know D.C. has some trendy, newer wine bars, with state-of-the-art preservation systems and interesting wine lists. I was wondering if this has spilled over into Northern Virginia? If so, what are they called? If not, who has the best selections of wines-by-the-glass in NoVa. I'm an wine lover moving to the area soon, and would love to find some good spots. Also, any names/locations of top wine stores would be appreciated.
