I came back here from a long hiatus (not that I was after a regular but after an unfortunate incident in which an intoxicated associate got us kicked out of the bar, we'd been reluctant to show our faces). That being said, I really could take it or leave it because my other experiences here have been fun but nothing to write home about (except the night that we got kicked out).
However I stopped in last Saturday (admittedly we were already happily buzzed) and I had a great time. Good music and the crowd in particular was fun and not too pretentious so I had a blast. Of course there's a good chance that I was probably more than happily buzzed and was too intoxicated to give two craps about the crowd one way or the other.
Jacob P. gives some good advice on how to have a good time. My other suggestion is to come here after you've already gotten shitfaced at another bar (or three) and wrap up here. It worked for me.
