Hard Rock Cafe kicked off its annual World Burger Tour competition on Saturday to celebrate Hard Rock International Founders’ Day. Hard Rock Cafe chefs worldwide were challenged to develop unique burger creations that showcase elements from their regional cultures and personal taste.

From June 14 through August 5, these innovative recipes, including the Choila Burger, will be available exclusively for guests to try at Hard Rock Cafe Kathmandu. Choila Burger, developed by Biplov Maharjan at Hard Rock Cafe Kathmandu, is made with a fresh buffalo burger patty seasoned and seared, topped with house-made spicy Nepali choila sauce and a fried egg. It is served on a toasted bun with a cabbage-cucumber medley and is inspired by the traditional flavours of Nepal’s Newari cuisine.

This year’s competition marks an exciting first for Hard Rock, with the addition of chef, content creator and brand partner Olivia Tiedemann as both a mentor and judge. Based on Tiedemann’s input, sales performance and guests’ votes on social media, the top five burger recipes will be selected and announced later this summer. Then the five finalists will become available globally at Hard Rock Cafe locations for all fans to experience for a limited time before one final winner is selected.

The first Hard Rock Cafe at Old Park Lane in London opened on June 14, 1971. Launching this competition on Founders’ Day celebrates how the brand has evolved over 54 years into an iconic entertainment, hospitality and lifestyle company with over 300 Hard Rock Cafes and Rock Shops, Hotels, Resorts and Casinos worldwide.
