Some hotels and restaurants may accept foreign currency, however, in most cases you will need to exchange your currency for rupiahs. Most major business centres provide currency exchange facilities and banks can also exchange your foreign currency, as can some hotels. If you exchange your foreign currency with a street money changer, ensure you count and recount your money yourself to avoid sneaky rip offs.
