We always try to get to El Quincho to have lunch when we are travelling between Posadas and Iguazú in Misiones Province. They serve a great grilled lunch "al galeto" (pieces of meat cooked on swords, brochette style, over a charcoal fire). The salad bar offers a nice selection and it's all you can eat off the grill: several cuts of beef, pork, chicken, sausages, etc. The chicken is to die for! You also get french fried yucca (mandioc) as a side. Yum!
