Mercado Municipal Huacrachuco

Unsure if this is the correct location. There was a scene on the show where Tony and Eric visited Mercado Central on Calle San Martin in the Marañón Canyon where they bought food to cook to feed their host, Don Elioberto, and his family. They made chicken and shrimp with peppers and onions, along with mashed potatoes and traditional Aztec hot chocolate. I could not find a Mercado Central on a street with this name on the map.
