We tried London's controversial prison-themed cocktail bar

Business Insider visited Alcotraz, a controversial Alcatraz themed pop up cocktail bar where patrons are served by mixologists dressed as prisoners.

The pop up is a "Bring Your Own Booze" bar, meaning that visitors have to bring in their own unopened bottles of their spirit of choice.

On arrival guests have to "smuggle" in their own alcohol, it's then taken by mixologists who make personalised cocktails for you.

We spoke with Alcotraz' founder, Sam Shearman about the backlash he has received around the prison theme.
