The alcohol being consumed at the bar by The Mad Turk is "Black Death" vodka, popularized in the early 1990s by Slash from the band Guns N' Roses. Not readily available in the US, the bottle labels were meticulously recreated for the film from a bottle purchased in 1991.
The shirt being worn by James Aaron Tecumseh Sinclair, who plays the bartender Troy, is from The Black Cat Lounge, a now defunct biker bar in Austin, Texas.
