Many places in Purcamarca were advertising meals but every place we tried was either too expensive or not-serving food that day (for some unknown reason). A friendly man on the main square recommended Restaurant Algarroba (named after the 500 year old Algarroba tree beside the church) to us, and I´m glad we asked as it was very cheap, good value and we got to try some local specialities such as tamales and humitas. It's on the street running west of the main sqaure from the church.
The restaurant is clearly one of the nicest in town. Spacious in colonial style.
This is about one block off the main plaza in town. Emphasis is on Andean cuisine- lamb and llama for meats..potatoes/beans and quinoa. Portions were generous and the food was delicious. (Remember, here you are at altitude, you dont need large portions!!!)
Favorite Dish: Llama carbonada
Twice I tried llama when i was in this part of the country with somewhat different results. Llama that was part of a caserole like dish was delicious, sliced and very nice. Llama served like a steak ended up being less pleasant an experience. The meat itself is tasty but rather fibrous, so its a LOT of chewing.
the benefits of llama is that it has no cholesterol at all.
