Jon O'Connor, 27, Sean McAteer, 22 and David Monaghan, 27, were named national champions in the flairing category.
The team will now open the European Bartender Championships which takes place at T G I Friday's Royal Exchange restaurant in Manchester on October 9.
Flairing is the art of theatrical bartending which involves juggling and spinning bottles whilst making a cocktail.
It was made famous by Tom Cruise in the film Cocktail – who was taught by T G I Friday's bartenders.
The trio added a musical twist to their routine, with David and Jon both beatboxing as well as flairing.
Jon said: "It's fantastic to be part of such an incredible event – the biggest and best bar championship final ever. We can't wait to open the European final in front of some of the best bartenders on the continent.
"Whilst flairing is fun, it also demonstrates the great bartending skills that exist at Friday's. To be recognised as one of the best in the business is a huge achievement."
