Whether or not you indulge in alcoholic beverages, you can't leave Guatemala without trying a limonada con soda: fresh-squeezed lemonade made fizzy with soda water. Licuados (fruit shakes) are also delicious. You can order them with water or milk (leche). In Guatemala, the latter is safer, unless you're certain the restaurant uses purified water. Also avoid ice (hielo) unless it's purified.
