The Turkish-Australian co-host of MasterChef Turkey is adding to his Sydney food empire, opening kebab bar Tombik in January.

Sydney-based chef Somer Sivrioglu is currently in Turkey, where he has become a household name as co-host of the local version of the TV cooking show, but his business partner, Tarik Koni, confirmed Tombik will slot into a vacant site in the back streets of Barangaroo, not far from the duo's upmarket Anason restaurant.

The 45-seat kebab bar will focus on Istanbul-style street food, particularly its signature tombik sandwich, using flatbread straight out of a wood-fired oven.

With planned fillings to include beef rump, lamb belly and falafel, they are hoping to scotch the reputation doner kebabs have gained in Sydney as a mass-produced, after-drink option. Expect a beverage list littered with Turkish wines and beer and the pickled turnip drink salgam.

Sivrioglu and Koni's Origins Dining Group has been busy, now at the build phase of a vegetable-focused eatery near Wynyard Station – and hunting new sites to relocate its recently closed Balmain eatery, Efendy.

"It (Tombik) will be a place to stop by any time of day or night for some delicious drinks and snacks with friends," says Koni. When it opens early next year, the venue will mix velvet banquettes, vegan leather countertops and Ottoman-inspired tiles.
