I've been to Union Drinkery a bunch of times since it opened, it's my favorite new bar in our area. The spot, owned by the same folks as A&D and Sundevich (and Small Fry) at 3216 Georgia has a good vibe, nice folks and tasty, not expensive drinks.
They also have a big back patio, but I'd never ventured upstairs, and the other day I was glad I did -- it's basically another bar.
It's a big space that looks like it used to be a townhouse, with little nooks and rooms and black-painted closets with art in them. There's lots of space for a big group or an intimate date, plus another bar, games and a big Jenga. I took a couple (blurry) shots, but they don't do it justice, it's really neat. Check it out.
