During his ten years as a burger chef, Rocco Saleha, 27, always wanted to make the tallest burger possible.
When he opened his own shop at Urbanstraße four months ago, he finally got to turn his dream into a mouth-watering reality.
"This is an idea that I wanted to do for a long time but I didn't have the money for it," he told The Local.
"You can't just do what everyone else does. I thought, what can I do that would make a name for myself? That's why I chose to make the tallest burger there is."
Wedged between six buns, the King Kong burger costs €15, takes two people to build and needs four kebab sticks to hold it up.
The organic, ground beef is pounded into five 120 gramme patties right before your eyes.
Then they're flame grilled and topped with bacon, salami, halloumi cheese, onion rings, nachos, jalapenos and lots of cheddar.
The result is a real work of art, and simply delicious. The Local’s reporter got about a third of the way through it before bringing it back to the office to share with some very happy colleagues.
But can anyone manage it all on their own?
"You have to be hungry, have fun eating and have lots of time," Rocco said. "You can't just eat it in 15 minutes. It takes a while.
"I have eaten the whole thing. I've also sometimes not managed it. It depends on how hungry I am."
And when 30 cm just isn't enough, Rocco is willing to make it even taller "upon request”.
One particularly hungry customer wanted a 50 cm burger. No problem.
Lily Burger also has a pleasant surprise in store for vegetarians and vegans.
It has gluten-free burgers, falafel burgers and tofu burgers, alongside vegan bacon, vegan cheese, vegan salami and 30 vegan homemade sauces.
