This area has no great food, but it has plenty of adequate food; simple choices are the best. The restaurant at the ruins' visitor center serves decent snack food. The hotel restaurants mostly do a fair job, though they are more expensive than they should be. In the village of Pisté, you can try the Hotel Chichén Itzá or one of the restaurants along the highway that cater to the bus tours (best during early lunch or regular supper hours, when the buses are gone).
