This is a video of bartender Po Hseng Hsu, who's been dubbed the Bruce Lee of flair bartending. He does have some pretty cool tricks, I especially like when he spins the bottle on the cup. I could watch stuff like this all day, just as long as that's not my drink I'm waiting for. *twenty minutes of bottle flipping later* Cool cosmo bro but I just ordered a beer.
Keep going for the video.
Thanks to GodzAngel, who really just wanted a hard cider.
