William went on to declare his handiwork "good enough for an advert" and onlookers were delighted to see the royal couple good-naturedly engaging in the fun.
The Duke and Duchess met Northern Irish Olympian Dame Mary Peters at the venue and congratulated her on her recent appointment to the Queen's Order of the Garter in a speech to guests.
In his closing address, William referenced his bartending prowess remarking: "All that remains is to say thank you to all of you. On the assumption that the bar staff are more skilled than Catherine and I at pulling pints, I've no doubt you'll have a brilliant evening."
The Cambridges are in Northern Ireland on an official visit focusing on children and young people's community initiatives.
