One of the most popular drinks in Vietnam is fresh coconut water, which is widely available from roadside stalls. Coconut water is not only refreshing, but it also provides a welcome source of hydration in the country's tropical climate. Another popular drink is 'tra da', which is made from iced green tea and milk. This refreshing beverage is perfect for hot weather, and can be found at many cafes and restaurants across Vietnam. For something a little different, visitors to Vietnam can try 'ruou de' - a type of rice wine that is often infused with various herbs and spices. Ruou de can be found in many bars and restaurants, and makes for a delicious way to relax after a long day of exploring Vietnam's vibrant streets.
