Honor Amongst Thieves is the coolest second-story bar I've been to! The ambiance is very dark and mysterious. If you've never been, you might have trouble finding it. The back stair well that leads you up to the bar makes you feel like you're an exclusive member entering the venue.
The drinks are really different as well. My friend got hers with cotton candy on it!
People who go, tend to stay for a while. Seating is pretty limited and there is not much space to move around or dance. It's a fun space for groups though.
