Time Out says
The battle of the burgers is back
Taste the city's most delicious burgers at this hugely popular festival, which sees the Strossmayer Square sizzle with culinary activity in late summer. Zagreb's best buger joints are represented here, so you can be sure you're sampling the finest patties available: 50 A Burger, RougeMarin and Submarine are highly recommended. Burgers are perfectly paired with local craft beer and there's a stellar line-up of live music to accompany the feast.
