Located inside the Mercado Coyoacán, Quesadillas Doña Lucha is a great stand for a delicious,…read morecasual, fast meal. They make quesadillas (obviously) and also tacos, sopes, chiles rellenos, and more. My husband and I stopped by a couple of weeks ago and had a couple of quesadillas, chiles rellenos, and horchatas. On the table are several different salsas and toppings for everything (crema, chiles, etc.) Everything was delicious. The quesadillas can be fried or grilled. I had a zucchini flower quesadilla and a chile relleno, too. My eyes were definitely bigger than my stomach, but everything was delicious. The service was great as well, and the stand is comfortable - and great for people watching with so many people working at, shopping at, and exploring the market.
