I love this dump; I will miss it if it ever gets put out of business by the corporate machine chewing up downtown Austin. The rumor of its imminent death has been going for at least 10 years now so I won't believe CD is closed till the building is bulldozed. Chain Drive is a seriously dank dive that purports to be a leather bar in name only. I have on occasion seen leather in there on a Friday or Saturday night but even then, that was not the norm. Its a friendly place where non-twinks, bears, chubs, punks, old guys, guys who like all of the above, and anyone else who doesn't feel comfortable in "mainstream" gay culture goes. The restrooms are nasty, no privacy - I don't know if that's supposed to cut down on cruising, or the owner is just too cheap to spring for doors and stalls. The patio furniture is all broken, and the place is more or less dead when there's not an event, but the drink specials are insanely cheap and the staff is friendly.
Pros: Cheap drinks, Great music, friendly patrons and staff
Cons: Seriously run down dive
