Really cool place to check out! The entrance is kind of tucked away behind a larger bar - you gotta turn the corner and walk past the other place to get to the Lab. The Lab looks very small when you walk in - probably because it's very dark, but there are large lounges both downstairs and on the right when you walk in.
The place seems to be exclusively staffed by mustachioed male hipsters, but overall they're all very personable and nice. The lack of lighting also does good to hide all the duct tape covering the ripped seating and the peeling paint on the walls - it's got a very grungy feel to it. Despite this, the staff there were all very attentive and friendly - our drink cups were whisked away from our hands the second they were emptied, and our little table tea candles (providing the little light we had) were promptly replaced when they began to even flicker.
The special they had the night we went (Saturday) was $3 Absolut vodka anything - mixed drinks, shots, etc. The bartender was very nice, and took orders very fast even when there was a mob of people waiting. Asked him to whip us something as a surprise and he made a very good grapefruit/club soda mix.
The little yard thing at the exit definitely seems to be a bit of a breeding ground for rowdy people and we got a little bit heckled as we left - the staff seemed to be buds with whoever they were and didn't do much.
This place definitely caters to the college crowd, and has a super grungy, hipster feel to it. Definitely has a lot of character.
