Smokin' Joe's Knockout Burgers serves butter-toasted buns with house-made sauces in Berea. The menu includes double-patty options like the Smokin' Joe — two beef patties with cheese, caramelised onion, roasted tomatoes, jalapeño, and secret sauce — and the Royale with Cheese, which adds gherkins and lettuce. The Tripswitch comes with double cheese, sriracha, and cheese sauce.

The kitchen has been operating since 2015, sourcing ingredients for its burgers. The buns are toasted in butter, and the sauces are made in-house. The restaurant is on Problem Mkhize Road in Essenwood.

Orders come in fast-food style, with no table service. The focus is on the burgers, which are the reason the place exists at all.
