Aguas Calientes is packed with restaurants catering to tourists: the offerings are usually very similar, and the prices are often too high for the quality of the food. The Tree House, however, is worth a visit. This restaurant is known for using traditional and organic ingredients to fuse local flavors with an Asian and Italian influence. Imagine grilled alpaca served with a traditional Andean potato and regional cheese pie and organic salad, or a quinoa risotto topped with lamb meat in a reduction of Andean corn beer and cilantro. For around 40 PEN, you can buy a lunch box to take with you up to Machu Picchu.
