Cuy is hard to find, when in Quito I had to get a taxi driver to help with the search, he went to a number of places before we found one. In a not very good part of town, apparently cuy is not for tourists.
The cuy was served more or less whole, cut into 4 parts. It had been skinned and partially gutted, but with head, teeth and feet still intact. It was awful, greasy and foul tasting. I had to drink a lot of chicha to get it down (

My last meal in Ecuador before heading to the airport. My guts took a couple of months to recover, not sure if it was the cuy or the chicha. Not recommending either...
