From Wikipedia

Businesses centered around tourism have flourished thanks to the tourism boom. There are a wide range of hotels, ranging from several 5-star hotels and chic resorts to hundreds of budget guesthouses. A large selection of restaurants offer many kinds of food, including Italian, Indian, French, German, Russian, Thai, Korean, Japanese, and Burmese. Plenty of shopping opportunities exist around the Psar Chas area while the nightlife is often vibrant with a number of western-styled pubs and bars.

Cambodia / Currency

The currency of Cambodia is ... the USDollar. Of course, this is not officially so. But in fact it is at least in Phnom Penh and in Angkor almost all goods and services are calculated and paid for in the US currency. But there is a national currency, even though you may not use it at all during stays in Phnom Penh and Angkor. The national currency is the Riel and there are bank notes of 100, 200 and 500 Riel.

Usually, this currency is only used instead of US Cents. You will pay, for instance, the drivers of Rickshas (called "Cyclo" or motorcycle taxis in Riel (500 to 1,000 Riel per trip), or the baguette at the local bakery (300 to 500 Riel per loaf).

Exchange

For travellers to Cambodia carrying US Dollars, in small as well as large denominations, there is no need to exchange currency at any time. You automatically acquire possession of Riel when paying in US Dollars and receiving the change below one Dollar in Riel.

For a marginally better rate, Dollars can be exchange into Riel at sidewalk money changers.

Currencies other than US Dollars can be exchanged at the banks. It is recommended to bring a sufficient amount of US Dollars for the entire duration of your stay.

Banks are usually open Monday to Friday (except on holidays) 7.30 am to 2.30 pm. Some banks also open on Saturdays from 7.30 am to 2.30 pm.
