I was thinking there probably needs to be a sticky for venue info that gets updated from time to time (to prevent repeated questions), but I started a list a couple years ago of all the places I've personally been to since I moved to Dallas/Fort Worth. Some of them are closed (could be re-opened as something else now), but I figured at least you'd have some insight on how many bars might be in a particular area or the type of crowd that goes there.
If anything seems inaccurate let me know and I'll change it. I can likely answer most any questions about a given spot on the list. Be warned, it's laughably un-short.
