This was the best meal of my trip to Chile. I found it in El Rincon de Pancho which is on the second floor food court of El Mercado Cardonal.
The catch of the day was perfectly pan-fried and served in generous portion alongside white rice and a cilantro-potato mixture. The potato side it was served with almost stole the show if the fish had not been so crispy on the outside and moist on the inside. Wish I could have this at least once a week. Delicious.
