Joe Mammone, the restaurateur behind Sarti and Il Bacaro, is expanding his portfolio, with a cafe and a rooftop bar set to join his South Yarra restaurant, Bar Carolina, on July 24.

Bar Carolina and its new siblings, Cantina Carolina and rooftop bar Tetto, share a Toorak Road address and a design aesthetic, courtesy of veteran architect Chris Connell (Il Bacaro, King & Godfree, Caffe e Cucina), but they're designed to complement rather than compete with each other.

Executive chef Matteo Tine (ex Grossi, Mr Ottorino) will serve a relaxed, Italian breakfast and lunch menu at the cafe, Cantina Carolina (Cantina for short). Expect "all the eggs" plus lunch dishes such as spicy fried chicken in a brioche bun with fennel slaw and pickles.

Upstairs at Tetto (Italian for "roof"), the focus will be on cocktails, champagne and European share plates such as cheese and salumi, caviar and flatiron steak. Mixologist Alex Dzyrart from London's Bar III is behind cocktails such as the Copacabana Fizz, a potent mix of dark rum, fig leaf, pineapple, clarified almond and prosecco.

It will feature a terrazzo-floored terrace with a retractable roof and a walnut-topped, porcelain-tiled bar. There's a separate space given an opulent fitout of leather and velvet booths, walnut and onyx tables, a large, custom-made Italian rug and hand-blown lights by Copper Design.

Cantina Carolina and Tetto will open at 48 Toorak Road, South Yarra, on July 24.
