Just off Plaza Santo Domingo, these ladies are preparing some of the best quesadillas in the city. Although you can find street food nearly everywhere, one indication of its quality can simply be figured out by counting the number of people waiting in line to get it. At this spot, I treated myself to a killer mushroom and cheese quesadilla along with a refresco (a soda). Eating it right there, standing on the sidewalk, is a great way to start up a conversation with locals or other travelers. This particular food stand is always busy. A friendlier group of ladies loving what they do won't be found elsewhere. ¡Buen provecho!
