Just for a little comparison:
Here are the three of us in Cozumel on November 13, 2012. When I was almost 6 months pregnant.
I have always heard about Pancho's Backyard, so we settled on that for our traditional nacho feast with Margaritas in Cozumel. We always order nachos wherever we go in Mexico. The serving of nachos was small, considering it was shared among three people. The margaritas were strong. I couldn't finish mine and I was a little buzzy walking back to the ship! After Panchos we took a few pictures in front of the giant xmas tree nearby.
