Also known as Thai limeade, it is an ideal beverage to accompany a spicy main dish. The Nam Manao drink consists of lime juice and sweetened water. As with most beverages served in the equatorial countries, it is a chilled drink that is meant to refresh you. As such, it is widely consumed during the warm days of the year. If you have the beverage from the street vendor, it will probably have sugar as the sweetener. On the other hand, if you are having it from a restaurant at a hotel or resort such as Anantara Hua Hin Resort, then it will most likely have sugar syrup added to it.
