I have only been once, so it's possible that I am not getting the full picture, but when I was there late-night on a Wednesday, the music was excellent (oh that slide guitar!) and the bartender was very friendly and funny, and also got us our drinks correctly and fast.
The atmosphere was a bit run-down and the lighting very dim, but it all was very comfortable. I really felt at home.
The beer selection is excellent. Given how tiny this place is, I was impressed that they had such a craft beer selection, including a cask.
I would go here again for sure, and given that I am not much of a bar person, that's saying a lot.
