Modern Australian cuisine showcasing the finest and freshest local beef, poultry and seafood.

Welcome to Cos 18 Leigh

COS Restaurant sits in an 1800s built, heritage listed building, situated in the historic and beautifully restored Leigh Street; a short walk from the West End’s major hotels and convenient to Adelaide’s central business district, theatre precinct and Central Market.

COS features an extensive wine list, showcasing predominantly South Australian wines from all major regions. You will find well known labels as well as carefully selected boutique wines that match perfectly with our menu. We also have a wide range of beers and spirits available.

Dine inside in the comfort of the restaurant or, weather permitting, alfresco out the front or in the beautiful courtyard. We can also cater for your next private function in the character-filled upstairs dining room.

Our team of experienced, dedicated and enthusiastic people pride themselves on creating memorable occasions. Their attention to detail and personalised service ensure a unique dining experience.
