Very good chicken
I lived in Foz de Iguazú a few years and with certainty the Confitera Jauense makes the best chicken leg with cheese from the three borders (Brazil, Paraguay and Argentina) tried by the majority of people visiting the city. This confectionery makes the best pies, crackers, and snacks in town. It has it's own parking, and a tea salon with 70 seats. Friends usually meet here to enjoy the delights, and chat in the evening.
