In London, the sacred happy hour could become obsolete thanks to a smartphone app that allows users to benefit from free cocktails in hip bars.

Drinki, as the app is called, has assembled more than 70 trendy London bars and pubs so far. Noteworthy drinking spots that have signed on include the famous Buddha Bar in Knightsbridge, The Big Chill in Shoreditch and the London Grind near London Bridge. The concept involves offering a free cocktail to any consumer that displays the app.

Concretely, all you have to do is download Drinki to your smartphone and look for the nearest bar to try it out. Users need to connect to Facebook to announce their presence in each bar via a “check-in” system. In one simple click, each user receives a free drink.

Cocktail fans can peruse the drinks on offer even before choosing their evening destination. The bars present their daily specials, be it a free glass of champagne, a Martini expresso etc. On average, cocktail prices start at 8 pounds (around 11 euros) in each affiliated watering hole.

The Drinki application is free to download on the App Store and Google Play. More than 10,000 drinks are served free of charge each week.
