Our mountain biking guide lives in Urubamba and this was his top restaurant recommendation. He recommended the Wasi location on the main square - he thinks the pizza oven is better than the one at this address. (Strangely, neither Google nor Trip Advisor seem aware of the Pizza Wasi on the main square, but it really does exist). Cheap and cheerful - extremely limited wine selection offset by willingness to do halfsie-pizza toppings for sharing. Great value.
