OK, so we go to all the wine bars in DC alot but usually don't go out in NOVA. But i've been hearing about some of the new wine bars & wine centric places to eat there and i need some opinions from some real wine lovers. If you were going out tonight and wanted to have several tastes of wine and some tapas-sized nibbles would you choose: Talulla, Grand Cru or Evo? I realize the first two are in ARL and the other one is in McLean but that's no biggy. We will have to drive a little to any of them. Also we want casual...did the dressy dinner thing last night. And for whichever you recommend do you need a res or could you walk in around 6:30 and sit at the bar or a small table and do your thing?
