Following two successful stores in Marrickville and Mount Druitt, Slim's Quality Burgers has arrived in the Sydney CBD with a new helping of affordable burgers and real ice cream thickshakes. Now open on Level 5 of Westfield Sydney, the third outpost for the burger chain comes just six months after it first launched at Marrickville Metro. Slim's is the creation of three ex-Betty's Burgers staff members. Like Betty's, the focus is on classic-style burgs rather than OTT numbers with the Shake Shack-style aesthetic swapped out for a 50s and 60s diner-style set-up. There's also a greater focus on affordability with a cheeseburger starting at just $6.50. The chain is all about a lean menu of options made with simple but quality ingredients. Burger-wise, customers can choose between original, cheeseburger, deluxe cheeseburger and 'the works' burgs all made with angus beef, plus five different chicken varieties — including a crispy fried or grilled chook — and a veggie option using a plant-based patty. "In the vast Australian burger market, we too often see venues that are built on gimmicks and fads," Slim's Director Nik Rollison said. "Whether it's the cheesiest burger or doughnut buns, we think Aussies have come full circle and want something that is simple, affordable and made from only the highest quality ingredients." Sides focus on fries either with sea salt, loaded with cheese and grilled onion, or featuring maple-smoked bacon. As for those sundaes, they come in hot fudge, salted caramel and strawberry flavours. And to wash it all down, there are spiders — because plonking a scoop of ice cream in some soft drink never gets old — or chocolate, vanilla and strawberry thickshakes. With CBD lunch options increasingly rising in price, the simple but high-quality approach to burgers is sure to be appealing to inner-city office workers. Slim's Quality Burgers new CBD outpost is located at Level 5, Westfield Sydney, corner of Pitt Street and Market Street, Sydney. It's open 11am–7pm Sunday–Wednesday and 11am–8pm Thursday–Saturday.
