But now Pizza Hut is asking its customers to order their meals in a whole new language.

To mark World Emoji Day this weekend (17 July) the chain has translated its entire menu in to emoji for a limited time only.

Diners will be encouraged to crack the code and order in emoji language, but can still request the original English menu if it all gets a bit confusing.

The special menu will be available at six Hut’s nationwide from 13-17 July.

Kath Austin, director of HR and marketing at Pizza Hut Restaurants, said: "We have a huge focus on menu innovation and having already launched a brand new menu recently, we hope customers enjoy decrypting the emoji version as much as we did creating it!"

Participating restaurants include The Strand London, Birmingham Bullring, Liverpool Paradise Street, Edinburgh Hanover Street, Manchester Fountain Street and Cardiff Queens Street.

The emoji menu is the latest unusual project from the chain, after it trialled a ‘subconscious menu’ in 2014 and craft beer-infused pizzas earlier this year.

It comes after Aloft Hotels launched an emoji room service menu in the UK​, allowing guests to order hangover kits and toiletries by texting different emoji combinations to staff.
