One of the town's better restaurants, Las Mestizas serves up decent Yucatecan fare. There's indoor and outdoor seating – depending on the time of day, an outdoor table may mean you'll be getting tour-bus fumes (and lines of people) to go along with that poc chuk (pork marinated in orange juice and garlic and grilled; M$115).
