If you arrive early in the afternoon, most of the town will be closed for siesta. Perhaps you want something to eat or a cold drink. Near the north end of town, along the main road that you walked in on is Hostal. At Frances which stays open and may have food available. A few hundred meters further, on the opposite side of the road, is a fully stocked (and air conditioned) grocery store where you can purchase supplies for the next day’s lunch or for a quick snack before dinner.
