We have a winner - but you are from Brazil so that gives you an advantage. These are indeed cuy which are apparently a delicacy in Ecuador. Most simple meals (chicken, rice, and salad) are around $3 but cuy was $17.
For those not familiar with cuy (as I was) - let me just say that those are particularly large guinea pigs.
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
