"Quesadillas Maria Isabel has been around since 1967, well before luxury boutiques and high-end art galleries took over the pricey Polanco neighborhood. The quesadillas here are prepared by folding raw corn tortillas in half, filling them with ingredients like cheese and chicharrón, and frying them. Go with one potato and one traditional cheese, which are just $2 each and served with a heaping side of sour cream and homemade green salsa. You’re not eating here for the vibes (there’s no music, the chairs are plastic), and it’s cash only, so come with a few pesos in your pocket." - Guillaume Guevara
