Book NowAbout Jumbo
Tucked into Adelaide’s business district, Jumbo delivers authentic smashburgers with a hard-seared crust and serious kitchen discipline. It runs on an industrial layout and a compact menu where every detail counts. Burger loyalists talk up the spicy Chilli Smash—dripping with house-made sauce—alongside a massive fried chicken thigh sandwich and a crisp fish burger. The sides pull equal weight, pairing ranch-dusted fries and blooming onions with house ranch, plus mash and gravy finished with crackling chicken skin. Inside, a tight room gets full table service, giving CBD lunch crowds and dinner drop-ins an easy sit-down upgrade.
