Making cocktails isn't just about flair - bottles spinning through the air as the bartender puts on a show. It's about precision, perfectionism and people skills.

Ruth Alexander meets three world-class bartenders to hear stories about their most glamorous customers, the dangerous ones, and what it takes to make the perfect drink.

Hear about the highs and lows; from the glamour of working on a movie set to the what happens when customers turn nasty. What's it like to make this challenging job your career?

Plus of course: how to make the perfect martini! (The answer might surprise you!)

Producers: Lexy O'Connor and Izzy Greenfield
