Cheap food starts at your hotel. Is breakfast included in the rate? If so, eat as much as you can comfortably consume. You might not see a breakfast as sumptuous as the one pictured above at La Luna Azul Bed and Breakfast in Playas del Coco, Costa Rica. But if you were taught that breakfast is the day's most important meal, this should not be difficult! If you're not usually a big breakfast eater, push yourself to eat now and save on lunch costs.
