The best Qusadillas EVER!
We discovered early on that the best and cheapest places to eat are in the markets where the locals do-- NOT in the tourist markets. In the heart of the market in San Cristobal, Mexico we found a place that sold HUGE Quesadillas, filled with melted cheese and meat "al pastor" (the best kind!), for only a few pesos! we ate there pretty much every day while we were there: nothing else compared!
