We went to the Cogas restaurant 3 times in our 2 week stay in Cagliari. The first time we had the aperitivo which consisted of a drink and a generous tasting platter of local food (didn't need any more food afterwards). It was so good we went back a second time, again for aperitivo. The third time we selected main courses from the menu, dishes from the local region. The food is delicious and great value. The service is good and the staff are friendly and welcoming. Well worth a visit and we will definitely be back there when next in Cagliari.
