Burger Theory Union Street

Burgers exploded onto the food scene in Adelaide in a big way. But Burger Theory is here for the long haul. A desire for better American-style burger options in Australia led to a successful food truck experiment, which then became a bricks-and-mortar business in the East End in 2013.

After dramatic increases to the price of beef and some thinking about sustainability, owners Robert Dean and Dan Mendelson removed all beef and pork options from the menu in early 2018.

Now you can choose from two vegetarian felafel burgers, chipotle chicken, and three meaty burgers with highly caramelised "smashed" 90-gram patties that take their cues from burger juggernauts Shake Shack and In-N-Out Burger. With one difference, that is – the patties are made mostly from kangaroo meat, with some fattier cuts of beef mixed in to maintain the “golden ratio” of 80 per cent meat and 20 per cent fat. Long-standing beef supplier Richard Gunner of Something Wild grinds the mixture, which is sandwiched between a potato bun imported from America (the buns are hard to find here).

Kangaroo isn’t the only native ingredient on offer. Karkalla (aka pigface – a native succulent) substitutes pickles in the cheeseburger and there's wild-boar bacon jam.

There's also frozen custard and two rotating draught beers.
