Slim’s Quality Burger Sydney

Slim’s – a burger chain launched by the three founders of Betty’s burgers – is pitched as Australia’s answer to America’s In-N-Out Burger. Like the Marrickville original, this CBD location is big, light and airy. Customers sit on cherry-red banquettes; bulbous light fixtures read “pop”, “gulp” and “chomp”; and a Perspex window looks into the kitchen so you can see your burger being prepped.

The cheapest burger on the menu is $6.50 (for the cheeseburger), with the most expensive ($9.50) being “the works” burger or a chicken club burger. All the beef burgers are made with Angus beef patties. Other options include the “deluxe cheeseburger”, which comes with a beef patty, grilled onion, cheese, ketchup, mustard and pickles; a fried-chicken burger with cheese and mayo; and a veggie burger with vegan garlic mayonnaise.

Chips are hand-cut on-site and ice-cream for sundaes and thickshakes is churned on- site each day.

Fries are similarly well-priced – $3.50 for a small or $4.50 for regular. Victorian-grown potatoes are washed and hand-cut in-house every day, fried with the skin on and sprinkled with pink Himalayan sea salt. Loaded options – including bacon and cheese, and cheese and onion – are also available.

Supremely thick shakes come in chocolate, vanilla and strawberry, or you can kick it old-school with a spider.
