I've added some additional information at the bottom of the page the link leads to from some of my experiences. I've been sarging in Austin a whole lot lately and asked to contribute a review of venues there.
**Note: Since the article was written; the Liars Den closed, but was successfully sarged during a bootcamp. I picked up one of the bartenders.
Just keep your eyes open on what pops up in that location as the 3 story layout is excellent for approaching and isolating your target for closes.
