We've been to Tree House for dinner, recommended by our hotel. It was late nigh (almost 10PM) and they were fair enough to ask how many people we were when we arrived. We're two and they could attend us. And even though I know they were closing, hey attended us with a smile in their faces. It was a great surprise to find this place there.
The atmosphere is very cozy, service is excellent and the food was amazing, I had a quinoa risotto with chicken that was of the best I had in Peru. My hubby had alpaca with pasta and was also delicious.
After a tiring and complicated day for us, Tree House changed our mood!
And, it's not cheap, but its price is accordingly with similar restaurants in Peru. And I believe is the best place to eat in Aguas Calientes, considering that all other restaurants in the city cost more or less the same and offer nothing as close as Tree House. Just go there!
