Komo Quieres, is an amazing good value Argentina restaurant in Can Roca just out side Sitges.
They serve a menu of the day for 14€. No starter but they instantly bring declivous olives and bread. Ask for the olive oil as this is amazingly fruity and very high quality from Siurana.
Great selection of different cuts of beef all explained to you at the table by the waiter as to where exactly they are from on the cow that is. Plus chicken and fish dishes and amazing pork ribs with excellent creamy mash potatoes. All the meat is accompanied with a different and interesting salad or vegetable dish. The wine is international and excellent I have often drunk wonderful Australian Merlot here and bought bottles to drink at home the white is fantastic too.
