Test Despite of the fact that Vietnamese government attempts to outlaw the practice, the US Dollars still acts as an alternative currency which is almost completely interchangeable with Vietnam Dong. Many prices, especially for hotels, tours and expensive restaurants, are still quoted in USD, though you can pay in dong if you’d rather - just check what exchange rate they’re using.
For everyday expenses, we recommend you carry a mix of US Dollars cash and Vietnam Dong. For larger items or when the exchange rate works in your favour, use dollars. For cyclos, local food stalls and small purchases, it’s best to use Vietnam Dong. In either case, make sure you always have a stock of small notes so that there is no need to worry about change.
