I think they have one of the better selections in NoVa. There is plenty of good beer to choose from and most of their stuff is rotated regularly. I usually go to norms when I am looking for fresh ipas. The only down sides to Norms is since they started twitter/facebook posts limited releases are usually gone in half in hour if that. Also because they are a small beer/wine store in Vienna their prices will usually be a dollor or two higher than the bigger stores.
I had dinner at the Merrifield Lost Dog Cafe last night and they had RuinTen with a two-bottle limit -- one-half case in sight. Sorry, I didn't note the price (I had gotten my RuinTen at Norm's on Friday).
RWB was selling them at $10/bottle. Westover Market and Lost Dog in Arlington got them as well late last week (unknown and 1 bottle limit respectively) and were cheaper than RWB. Westover also had it on tap as of last Friday, i'm sure it's kicked by now but absolutely delicious from a keg!
