Though their rise has been meteoric, it has not been without setbacks. One month after opening, the founders were forced to close their doors because of the Covid pandemic.

Hundred Burgers survived by temporarily becoming a delivery service, but eventually it  expanded across Valencia, where it has four sites, as well as to the capital city of Madrid, where it has three.

What makes the best burger in the world? The chefs start off every morning by baking demi-brioche bread buns in-house. The dough is fermented, kneaded and baked in their workshop, as the restaurant is keen to avoid serving frozen bread. Dry-aged Galician blond beef is then chopped up and formed into burgers by hand.

The most popular item on the Hundred Burgers menu is the Singular, which is topped with cheddar cheese, “Mum’s” barbecue sauce, bacon, caramelised onion and Camembert sauce. One of these will set you back €11.50 at any of their restaurants.

Other restaurants that made the top five were Au Cheval in Chicago and New York, Holy Burger in São Paulo and Funky Chicken Food Truck in Stockholm. Burger & Beyond, based in Manchester and London, missed out on the top five by just one spot.
