The El Perro Negro restaurant in Glasgow opened in 2018 and soon became one to watch, as it was frequently featured in blogs and polls as the place to go for the city's best burger.
Soon the burger specialists, led by founder Nick Watkins, were accruing national attention.
When they entered the National Burger Awards in 2019 with their signature Top Dog burger they beat the competition and took the crown for the UK's best burger.
